KEY FUNCTION

Hold Key
Data Hold mode makes the meter stop updating the display. Enabling Data Hold function in auto range mode makes the meter switch to Manual ranging mode, but the full-scale range remains the same. Data Hold function can be cancelled by changing the measurement mode, pressing RANGE key, or push HOLD key again.
To enter and exit the Data Hold mode
1. Press HOLD key (short press). Fixes the display on the current value, DH is displayed.
2. A second short press returns the meter to normal mode.
Select Key
1. Switches between dc and ac voltage or current.
2. Disables automatic power-off feature.
Battery Saver
The Meter enters the “sleep mode” and blanks the display if the Meter is on but not used for 30 minutes. Press the HOLD key or rotate the rotary switch to wake the meter up. To disable the Sleep mode, hold down the SELECT function key while turning the meter on.
Beeper indication
When press the function key and if it is valid, a beep will be emitted. The buzzer will sound five times one minute before auto power off. And a long sound to show the auto power off. In the continuity measuring status, if the resistance is smaller than 50Ω,the buzzer will sound.
Data Hold;
Diode Test;
Continuity Buzzer;
Auto Power Off.
