User’s Guide 600A True RMS AC/DC Clamp Meter Model 38389 Safety International Safety Symbols This symbol, adjacent to another symbol or terminal, indicates the user must refer to the manual for further information. This symbol, adjacent to a terminal, indicates that, under normal use, hazardous voltages may be present Double insulation SAFETY NOTES Do not exceed the maximum allowable input range of any function Do not apply voltage to meter when resistance function is selected. Set the function switch OFF when the meter is not in use. Remove the battery if meter is to be stored for longer than 60 days. WARNINGS Set function switch to the appropriate position before measuring. When measuring volts do not switch to current/resistance modes. Do not measure current on a circuit whose voltage exceeds 600V. When changing ranges using the selector switch always disconnect the test leads from the circuit under test. Do not exceed the maximum rated input limits. UL A UL mark does not indicate that this product has been evaluated for the accuracy of its readings. 2 38389-en-US_V2.8 4/15 CAUTIONS Improper use of this meter can cause damage, shock, injury or death. Read and understand this user manual before operating the meter. Always remove the test leads before replacing the battery or fuses. Inspect the condition of the test leads and the meter itself for any damage before operating the meter. Repair or replace any damage before use. Use great care when making measurements if the voltages are greater than 25VAC rms or 35VDC. These voltages are considered a shock hazard. Remove the battery if the meter is to be stored for long periods. Always discharge capacitors and remove power from the device under test before performing Diode, Resistance or Continuity tests. Voltage checks on electrical outlets can be difficult and misleading because of the uncertainty of connection to the recessed electrical contacts. Other means should be used to ensure that the terminals are not "live". If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

III 6 38389-en-US_V2.8 4/15 Operation NOTICES: Read and understand all warning and precaution statements listed in the safety section of this operation manual prior to using this meter. Set the function select switch to the OFF position when the meter is not in use. AC/DC Current Measurements WARNING: Ensure that the test leads are disconnected from the meter before making current clamp measurements. 1. Set the Function switch to the 600 or 400A range. If the range of the measured is not known, select the higher range first then move to the lower range if necessary. 2. Select AC or DC with the AC/DC button. Press the zero button to zero the meter in the DCA mode only. 3. Press the trigger to open jaw. Fully enclose one conductor to be measured. 4. The clamp meter LCD will display the reading. No Yes AC/DC Voltage Measurements 1. Insert the black test lead into the negative COM terminal and the red test lead into the positive V terminal. 2. Set the function switch to the V position. 3. Select AC or DC with the AC/DC button. 4. Connect the test leads in parallel to the circuit under test. 5. Read the voltage measurement on the LCD display. Resistance and Continuity Measurements 1. Insert the black test lead into the negative COM terminal and the red test V lead into the positive terminal. 2. Set the function switch to the •))) CAP position. 3. Use the multifunction button to select resistance. 4. Touch the test probe tips across the circuit or component under test. It is best to disconnect one side of the device under test so the rest of the circuit will not interfere with the resistance reading. 5. For Resistance tests, read the resistance on the LCD display. 6. For Continuity tests, if the resistance is < 30, a tone will sound. 7 38389-en-US_V2.8 4/15 Capacitance Measurements WARNING: To avoid electric shock, discharge the capacitor under test before measuring. CAP Position. 1. Set the function switch to the •))) 2. Press the multifunction button to select the capacitance function. 3. 4. Insert the black test lead banana plug into the negative (COM) jack and the red test lead banana plug into the positive jack. Touch the test probe tips across the part under test. 5. Read the capacitance in the display. 6. The display will indicate the proper decimal point and value. Temperature Measurements WARNING: To avoid electric shock, disconnect both test probes from any source of voltage before making a temperature measurement. 1. 2. 3. 4. CAP Set the function switch to TEMP. Insert the Temperature Probe into the negative (COM) and the positive jacks, making sure to observe the correct polarity. Touch the Temperature Probe head to the part whose temperature you wish to measure. Keep the probe touching the part under test until the reading stabilizes (about 30 seconds). Read the temperature in the display. The digital reading will indicate the proper decimal point and value. WARNING: To avoid electric shock, be sure the thermocouple has been removed before changing to another measurement function Data Hold To freeze the LCD meter reading, press the data hold button. The data hold button is located on the left side of the meter (top button). While data hold is active, the DH display icon appears on the LCD. Press the data hold button again to return to normal operation. Peak Hold To hold the highest reading on the LCD, press the peak hold button. The peak hold button is located on the left side of the meter (bottom button). The meter reading will not change as readings change, rather it will only display the highest reading encountered since the peak hold button was pressed. Press the peak hold button again to return to normal operation. 8 38389-en-US_V2.8 4/15 Maintenance WARNING: To avoid electrical shock, disconnect the meter from any circuit, remove the test leads from the input terminals and turn OFF the meter before opening the case. Do not operate with open case. Cleaning and Storage Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents. If the meter is not to be used for periods of longer than 60 days, remove the battery and store it separately Battery Replacement 1. Remove the Phillips head screw that secures the battery door. 2. Open the battery compartment 3. Replace the 9V battery 4. Replace and secure the door. Temperature Probe Replacement The replacement bead wire probe with banana plug connectors is p/n TP873. To use type k probes with a mini plug connector requires a mini-plug to banana plug converter. 9 38389-en-US_V2.8 4/15 Warranty FLIR Systems, Inc. warrants this Extech Instruments brand device to be free of defects in parts and workmanship for one year from date of shipment (a six month limited warranty applies to sensors and cables).
