Operating Instructions
Power ON/OFF
Press the Power button to turn the instrument on. Press this button again,
holding for one second to turn the instrument off. When the instrument is
on, it will begin an internal self-diagnosis at which time the full screen will
be displayed. Once complete, the instrument is ready to be used.
Automatic Power-Off
As a default the instrument will be set to automatically turn itself off
after10minuteswithoutanyaction.Followthestepsbelowtoturnthe
Auto-Power Off function off.
1. Be sure the meter is powered off.
2. PressboththePOWERandmA%/Vbuttonssimultaneously.
The display will indicate the symbol ‘AP-XX’.
3. Press the button to activate or deactivate the Auto-Power Off
function. ‘AP-OF’ indicates that there is no automatic power-off
functionset,and‘AP-ON’indicatestheautomaticpower-off
function is activated.
4. Turn the meter off to save the setting.
Output Function
The output terminal of the instrument can produce DC voltages set by the
user or simulating resistance.
Do not apply any voltage to the output terminal during the operation.
If any improper voltage is applied to the output terminal, it will cause
damage to the internal circuits.
