Page 3: Safety
Safety • Read this manual before using the meter and follow all safety guidelines. • Use the meter only as specified in this instruction manual. Otherwise the meters protection may be impaired. • Never use this meter on a circuit with voltages greater than 750Vrms @ 50/60 Hz. • Do not operate the meter if the body or test leads look damaged. • Check the function selector range switch and make sure it is at the correct position before each measurement is taken. -

Page 8: Operating Instructions
Operating Instructions Data Hold Function Press the HOLD button at any time to hold the current reading. To release the data being held, simply press the HOLD button again. Peak Hold Function This meter is designed with 1ms peak hold function at ACA, ACV, DCA and DCV ranges. Before performing a peak hold operation, a calibration process must be completed first. To do this, press and hold the PEAK button for 2 seconds. "CAL" will display on the LCD and the offset will be calculated and kept in the meter. After the calibration is complete, you can choose P+ or P- by pressing the PEAK + HOLD buttons to keep the peak reading. To return the meter back to normal operation, press the PEAK button for 2 seconds. When the function range changes, the meter will require another calibration for peak measurement. -
Page 9: Rel Function
REL Function This meter is designed with REL function at ACA, ACV and DCV, DCA ranges. Press the REL button to change the zero to the current reading and the relative value will show on the LCD. Press it once again and the meter will display the relative zero point. This mode will also be indicated with a blinking REL symbol. Set the meter back to normal operation by pressing the REL button for more than 2 seconds. Measurement Procedures Current Measurement Switch the main function selector to proper current range. -
Page 10: Voltage Measurement
Voltage measurement Switch the main function selector to Voltage Range. Connect the Red test lead to the " " terminal and the Black one to the "COM" terminal. Choose AC or DC by pressing the AC/DC button. Measure the voltage by touching the test lead tips to the test circuit where the value of voltage is needed. Read the result on the LCD panel. Resistance measurement Ω Switch the main function to the " " range, verify that the power line is disconnected from the system. Connect the Red test lead to the " " terminal and the Black one to the "COM" terminal. Connect the tips of the test leads to the points where the value of the resistance is needed. Read the result on the LCD panel. -
Page 11: Continuity Test
Continuity Test Switch the main function to the " " range, verify Beeper that the power line is disconnected from the system. Connect the Red test lead to the " " terminal and the Black one to the "COM" terminal. Connect the tips of the test lead to the points where the value of the conduction condition is needed. -
Page 12: Frequency Measurement From The Terminals
Frequency measurement from the terminals Switch the main function to the " " range. Connect the Red test lead to the " " terminal and the Black one to the "COM". Connect the tips of the test leads to the points where the frequency of the voltage signal is required. Read the value one the LCD panel. Frequency measurement with the clamp Switch the main function to the " " range. Open the clamp by pressing the clamp-opening handle and insert the cable to be measured into the clamp. Close the clamp and you will find the reading on the LCD panel. -
Page 13: Battery Replacement
• When taking current measurements, keep the cable at the center of the clamp to yield a more accurate test result. • Repairs or servicing not covered in this manual should be performed only by qualified personal. • To clean the meter, periodically wipe the case with a dry cloth. Do not use abrasives or solvents on these instruments.
