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 dis- play 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” button 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 calibra- tion for peak measurement. MAX/MIN Function This meter is designed with a MAX/MIN function at ACA, ACV, DCA and DCV ranges. Press the “MAX/MIN” button once to set the meter to the MAX mode. Press it once again to set the meter to MIN mode.

Page 9: Measurement Procedures
Measurement Procedures Current Measurement Switch the main function selector to proper current range. Open the clamp by pressing the jaw-opening handle and insert the cable to be measured into the jaw. Choose AC current measurement by press- ing the “AC/DC” button for ACA readings. To measure DC current, choose DC measurement by pressing the “AC/DC” button. Wait for the reading to stabilize then press the “REL” button to reset the reading. Once completed, insert the cable to be measured into the jaw and read the value. Notes: Before taking this measurement, disconnect the test leads from the meter for safety. If the reading is difficult to read, push the “HOLD” button and read the result later. CORRECT INCORRECT Blue - 100/80/30/5... -
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 “... -
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 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.
