Do not use the meter if the meter/test leads appear damaged or if you suspect that the meter is not operating properly. The user should never be grounded when taking measurements. Do not touch exposed metal pipes, outlets, fixtures, etc. which may be at ground potential. The user should be isolated from ground by using dry clothing, rubber soled shoes, rubber mats, or other approved insulating material. Remove power to the circuit under test before cutting, unsoldering, or breaking the circuit. Small amounts of current can be dangerous. Use caution when working above 60V DC or 30V AC rms. Such voltages pose a shock hazard. When using the test leads or probes, keep fingers behind the probe's finger guard. Measuring voltage which exceeds the limits of the multimeter may damage the meter and endanger the user. Always recognize the meter's limits as stated on the front of the meter. International Symbols 3 380224 Ver. 1.5 5/05 Operation Voltage Measurements a. Connect the RED test lead to the "V/Ω" input jack and connect the BLACK test lead to the COM (-) input terminal. b. Set the rotary switch to the desired AC or DC voltage range. If the magnitude of the voltage is not known, set the switch to the highest range and reduce until a satisfactory reading is obtained. c. Connect the test leads to the unit under test (load, circuit, etc.) and observe reading on the LCD. For DC, negative polarity is automatically displayed. Resistance and Continuity Measurements a. Set the rotary switch to the desired resistance range or continuity position. b. Remove power to the circuit under test (external voltage across device under test will cause invalid readings). c. Connect the RED test lead to the "V/ " input terminal and the BLACK lead to the COM (-) input terminal. d. Connect the other ends of the test leads to the circuit under test. For resistance measurements, the LCD reading is the value of resistance measured. In Continuity mode, the audible alert sounds if the resistance measured is below 100Ω. NOTE: The 2000MΩ and 200MΩ ranges have a fixed 10-count offset. When the test leads are shorted together, the meter will indicate "10". This residual values (10MΩ on the 2000MΩ and 1MΩ on the 200MΩ range) must be subtracted from readings taken in these ranges. Diode Measurements a. Set the rotary switch to the diode position. b. Remove power to the circuit under test (external voltage across device under test will cause invalid readings). c. Connect the RED test lead to the "V/ " input terminal. d. Touch probes to the diode. A correct forward voltage drop is 0.6V (silicon diode) and 0.3V (germanium diode). e. Reverse the probe connection to the diode. If the diode is good, "OL" (overload) will display. If the diode is shorted, a value near 0mV will be displayed. f. If the diode is OPEN, "OL" will display in both measurement directions. Capacitance Measurements a. Set the rotary switch to the desired capacitance range. b. Connect the RED test lead to the "F" input terminal and the BLACK test lead to the COM (-) input terminal. c. Connect the test leads to the capacitor under test, observing polarity for polarized caps. d. Read the capacitance value in farads on the meter's LCD. Temperature Measurements a. Set the rotary switch to the desired temperature range (C or F). b. Connect a K-type thermocouple probe with banana jacks to the TEMP and COM input terminals. Observe proper polarity: The TEMP terminal is for the positive probe lead; COM is for the negative probe lead. c. Read the temperature from the LCD display. 4 380224 Ver. 1.5 5/05 Frequency Measurements a. Set the rotary switch to the "Hz" position. b. Connect the RED test lead to the "V/ " input terminal and the BLACK test lead to the COM (-) input terminal. c. Connect the test leads to the points of measurement and read the frequency value in hertz (Hz) on the meter's LCD. Phase Indicator Measurements a. Set the rotary switch to the "3 Ø RST" position. b. Connect the RED test lead to the "R" input terminal, the BLACK test lead to the "S" input terminal, and the YELLOW test lead to the "T" input terminal. c. Remove power to the 3Ø device before touching test leads to the measurement points. d. Attach test leads to the measurement points and apply power to the device under test. e. If the wiring is correct with regard to phase, the RST and "OK" LCD icons will appear and the audible tone will sound continuously. If the connection is incorrect, the "ER" LCD icon will appear. If the error icon (ER) is displayed, remove power to the device under test, reconfigure the wiring before applying power again, and test for correct phase. Repeat as necessary. Maintenance Battery Replacement The battery symbol on the LCD alerts the user of low battery voltage. Remove the test leads from the circuit under test before replacing battery. a. Remove the test leads and turn the meter OFF b. Remove the three (3) screws from the rear of the meter. Open the meter housing. c. Replace the battery with a 9V NEDA 1604 or equivalent, reassemble meter, and replace screws. Electromagnetic Interference Electrical noise or intense EMF in the vicinity of the meter may disturb the measurement circuit. The meter may respond to unwanted signals that may be present within the measurement circuit. Users should exercise care and take appropriate precautions to avoid misleading measurements in the presence of electromagnetic interference.
