6.5. Programming Procedure WARNING: Do not connect the unit to live voltage or charged cable. Note: The sample length of user wires must be between 1m and 100m in METER mode or between 3.3ft and 320ft in FEET mode. 1. Set the rotary switch from the OFF Position to the desired range, calibrate the meter as described in “Calibration Procedure”. -

5. Remove the insulation at both ends of the cable under test. Note: Make sure that the two conductors of the cable under test are clean and fully exposed, and that the insulation must be removed to make it easier for the test clip to fully clamp the cable, if desired, use grinding pads to clean the exposed cables. -
Page 12: Read Data
6.6.2. Read Data • When the meter is in the ready or test state, long press the CLR/READ button, the meter displays the last saved data, then press the UP/COMP or DOWN and FT/M button to show the previously saved data. -

3. Set the High/Low comparative value, short press the OHM/LEN/SET button to change the high limit comparative value or low limit comparative value. 4. Select the unit of resistance, after each long press on the DOWN and FT/M button, the unit will display “Ω, mΩ, kΩ”, the same group of high lowers comparative value should have the same unit. -

6.9. Bluetooth Function If the Bluetooth function is activated, the user can transfer data from the instrument to the Meter-X app. 1. Hold down the OHM/LEN/SET button while on the resistance mode after turing the meter on, “SET” appears on the LCD and “COMP” starts flashing. -
Page 15: Auto Off
9. Press the CLR/READ button to exit and return to the measurement interface. 6.12. Auto Off • The Meter automatically turns off after 10 minutes of inactivity when auto-off is active. • If the Meter has automatically shut down, restart it by pressing any key or turning the rotary switch. -
