Failure to observe warnings can result in severe injury. WARNINGS WARNINGS identify hazardous conditions and actions that could cause BODILY HARM or DEATH. When handling test leads or probes, keep hands and fingers behind the finger guards at all times. Remove test leads from the meter before opening the battery compartment or meter housing. Use the meter only as specified in this User Guide or accompanying Quick Start to avoid compromising the protections provided by the meter. Be sure to use the proper terminals, switch positions, and ranges when taking measurements. Verify the meter’s operation by measuring a known voltage. Have the meter serviced if the meter responds unusually or if there are questions regarding the meter’s functional integrity. Do not apply more than the rated voltage, as marked on the meter, between terminals or between any terminal and earth ground. Replace blown fuses with fuses of the same type and rating as specified in this User Guide. Use caution working with voltages above 30 VAC RMS, 42 VAC peak, or 60 VDC. These voltages pose a shock hazard. To avoid misleading readings that could lead to electric shock and injury, replace the batteries as soon as the low battery indicator is displayed. Disconnect power to the circuit under test and discharge all high‐voltage capacitors before testing resistance, continuity, diodes, or capacitance. Do not use the meter in the presence of explosive gas or vapor. To reduce risk of fire or electric shock, do not use the meter if it is wet and do not expose the meter to moisture. Individual protective equipment should be used if HAZARDOUS LIVE parts in the installation where measurements are to be carried out could be accessible. CAUTIONS CAUTIONS identify conditions and actions that could cause DAMAGE to the meter or equipment under test. Do not expose the meter to extremes in temperature or high humidity. Disconnect the test leads from the test points before changing the position of the function (rotary) switch. Do not expose the meter to extremes in temperature or to high humidity. Never set the meter to the resistance, diode, capacitance, micro‐amp, or amp functions when measuring the voltage of a power supply circuit; this could result in meter damage and damage to the equipment under test. 4 EX36x‐en‐GB_V1.5 09/15 Safety Symbols that are typically marked on meters and instructions This symbol, adjacent to another symbol, indicates the user must refer to the manual or user guide for further information.

Operation CAUTION: Read and understand all of the Safety statements listed in the safety section of this manual prior to use. Powering the Meter 1. Turn the rotary function switch to any position to power the meter. Check the batteries if the unit fails to power ON. Refer to the Maintenance section for battery and fuse replacements. 2. Turn the function switch to the OFF position to power OFF the meter. 3. The meter has an Auto Power OFF feature (APO) where the meter switches OFF after 20 minutes of inactivity. When APO is enabled, the APO icon will show on the display when the meter is powered ON. To disable APO, refer to the next section. Note: The meter displays the battery capacity when powering up. The display will either show the word FULL (battery fully charged) or a percentage representing remaining battery power. The international segmented battery strength symbol is also shown on the display at all times when the meter is ON and when there is sufficient battery power to power the meter. Disable Auto Power OFF The meter will auto power OFF after 20 minutes of inactivity. To defeat this feature, follow the steps below. 1. With the meter OFF, press and hold the M (MODE) button and, while continuing to hold, turn the rotary function switch to any position to power ON the meter. 2. The display will show AOFF. 3. Release the button. 4. APO will now be disabled until the next cycle of power. Display Backlight With the meter powered ON, press the backlight button to switch the backlight ON or OFF. Note that excessive use of the backlight will shorten the battery life. Smart Data Hold To freeze the LCD meter reading, press the H (HOLD) button. While data hold is active, the HOLD display icon appears on the LCD. Press the H button to return to normal operation. The HOLD icon will switch OFF. The meter’s beeper will sound and the LCD will flash if the detected signal is 50 counts greater than the held reading.

Fig 4‐4 µA AC/DC CURRENT MEASUREMENTS 14 EX36x‐en‐GB_V1.5 09/15 Non‐Contact Voltage Detector WARNING: It is possible for voltage to be present in a circuit even if the meter does not beep or light the NCV LED lamp at the top of the meter. Always verify meter operation on a known live AC current circuit and verify that the batteries are fresh before use. The audible beeper sounds and the LED lamp at the top of the meter lights when the meter senses an electrical voltage field. If the meter does not emit a tone or light the LED in this mode, there is still the possibility that voltage is present. Please use caution. 1. Turn the function switch to the NCV position to access the Non‐Contact Voltage Detect mode. 2. Use the Lo/Hi button to select low sensitivity (160 to 1000V) or high sensitivity (80 to 1000V). The display will show Lo for low sensitivity or Hi for high sensitivity mode. 3. 4. 5. Note the voltage detection display icon on the display when in this mode. To test, place the meter near a source of electrical energy. Note that the tip of the meter offers the highest sensitivity. Note the audible tone and the LED light when a source of electrical energy is detected. Fig 4‐5 NON‐CONTACT VOLTAGE DETECTOR 15 EX36x‐en‐GB_V1.5 09/15 Resistance Measurements Cautions: Switch OFF power to the device under test before measuring. Do not test on circuits or devices where 60VDC or 30VAC is present. 1. 2. 3. 4. 5. Insert the black test lead banana plug into the negative (COM) jack. Insert the red test lead banana plug into the positive (V/Ω) jack. Turn the Function Switch to the Ω position. Use the M button to select the Ω icon on the display indicating resistance only (without the audible continuity icon showing). Touch the test probe tips across the circuit or part under test. It is best to disconnect one side of the part under test so the rest of the circuit will not interfere with the resistance reading. Read the resistance value in the display. The display will indicate the proper decimal point and value. If the reading is out of range, the OL display icon will appear. Fig 4‐6 RESISTANCE/CONTINUITY MEASUREMENTS Continuity Measurements 1. Insert the black test lead into the negative COM terminal and the red test lead into the positive terminal. 2. Set the function switch to the 3. Use the M button to select the Continuity mode. Look for the Continuity icon display. 4. Touch the test probe tips across the wire or circuit under test. 5. If the resistance is < 20 Ω, the beeper will sound and the LED lamp at the top of the meter will flash. The beeper and LED lamp will switch off if the measured signal rises above approximately 200 Ω. For an open circuit condition the meter will display OL. position. 16 on the EX36x‐en‐GB_V1.5 09/15 Capacitance Measurements WARNING: To avoid electric shock, remove power to the circuit under test and discharge the capacitor under test before measuring. Do not test on circuits or devices where 60VDC or 30VAC is present. 1. Set the function switch to the 2.

Fig 4‐7 CAPACITANCE MEASUREMENTS Relative Mode In Relative mode a reference reading can be stored with which to compare subsequent readings. Press the button to store the displayed reading in memory, this becomes the reference. The symbol will be displayed when the Relative mode is active. Subsequent readings will now be compared to the stored reference (Displayed Reading = Measurement minus Reference). Press the button again to exit the Relative mode; the Relative symbol will switch off. 17 EX36x‐en‐GB_V1.5 09/15 Diode Test 1. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive jack. 2. Turn the function switch to position. Use the M button to select the diode function if necessary (the diode and voltage symbols will appear on the LCD when in Diode test mode). 3. Touch the test probe tips to the diode or semiconductor junction under test. Note the meter reading. 4. Reverse the test lead polarity by reversing the red and black leads. Note this reading. 5. The diode or junction can be evaluated as follows: If one reading displays a value (typically 0.400V to 0.900V) and reverse reading displays OL, the diode is good. If both readings display OL the device is open. If both readings are very small or ‘0’, the device is shorted.
