3 Switching the Multimeter „ON“
Battery
Your multimeter works on 2 x AA size alkaline manganese bat-
teries per IEC LR6. They are provided with the multimeter.
Before you use the multimeter for the first time or after storage,
refer to section 17.1. Set the rotary knob (6) to other than the
„OFF“ position to switch the multimeter ON. Switch „ON“ is
acknowledged by an acoustic signal. All segments of the LCD
will be displayed as shown on page 2.
Note:
Electric discharges and high-frequency influence may cause
incorrect information to be displayed and block the measuring
process. Reset the multimeter by switching it OFF and ON
again. Otherwise, check the battery connections. Disconnect
the multimeter from the measuring circuit before you open it,
and refer to section 17.
Automatic Meter-OFF (MoFF)
The digital multimeter has a default auto meter-off function. If
the multimeter is idle for more than 15 minutes, the multimeter
automatically turns the power off. When MoFF happens, the
state of the multimeter is saved. The „MoFF“ (16) sign on the
LCD panel indicates whether the MoFF is enabled or not. In
some cases, the user might want to disable this feature. Power
ON the multimeter by pressing any of the push functions
except for the HOLD (8) and multifunction (5) pushbuttons.
After auto meter-off, pushing any of the push functions or
changing the rotary switch mode can turn on the multimeter
again. If the multimeter is re-powered by changing the rotary
mode, the saved state is cleared. If the multimeter is re-pow-
ered by push functions, the chip restores the saved state and
enters HOLD mode. The LCD displays the saved value.
Turning the multimeter OFF
To turn OFF the multimeter, set the rotary knob (6) to the „OFF“
position.
