HOLD function
The HOLD function freezes the currently indicated measured value to allow you to read it or to take the
record without rushing.
If you test live wires make sure that this function is deactivated before the measure-
ment starts. Otherwise, the measurement will be incorrect!
To switch on the Hold function, press the “H” button (10); an acoustic signal confirms this command and
“H” appears on the display.
In order to switch off the HOLD function, press the “H” button again or simply change the measurement
function.
Low imp. 400 kΩ Function
This function may only be used for voltages of a max. of 1,000 V and a max. of 3
seconds!
This function enables reducing the measuring impedance from 10 MΩ to 400 kΩ in the voltage measuring
range. Through the reduction of the measuring impedance, possible phantom voltages are suppressed,
which could falsify the measuring result.
Press this button (9) during voltage measurement (max. 1,000 V!) for a max. of 3 seconds. After release,
the multimeter has the normal measuring impedance of 10 MΩ . While the button is pressed, a signal
sounds and the display “WARNING!” appears.
Auto Power OFF Function
The DMM turns off automatically after 15 minutes if no button or switch is operated. This function pro-
tects the battery, saves battery power and extends the service life.
To reactivate the DMM after automatic shutdown, use the dial switch or press any button (apart from the
light button (9)).
The Auto-Power-OFF function is deactivated when the interface is activated so that the data connection
is not interrupted. This function remains inactive until the interface is switched off again.
