Operation Manual
12 GMC-I Messtechnik GmbH
Ð Turn the crank in the direction indicated by the arrow at a speed
which causes the signal LED at the upper right hand portion of the
display to light up and burn continuously.
Note
If the
signal LED is not lit, or if it flickers, test voltage is too low, i.e. too
little power is being delivered by the crank generator.
Measurement values are only valid if the
signal LED is continuously lit.
For high capacitance DUTs (cables, large machines and transformers),
continue cranking until the needle gauge has stabilized. The signal LED
must be continuously lit during testing. This may take as long as several
minutes, depending upon the capacitance of the DUT. Battery operation
is recommended in such cases.
8.4 Discharging the Device Under Test
The function selector must be switched from back to V, in order to dis-
charge test voltage from the DUT. Contact with the DUT must be main-
tained until the discharge process has been completed. The range selec-
tor switch can be left at its original setting. The crank need not be oper-
ated in order to discharge the device under test.
8.5 Measuring Voltage in the Crank Generator Operating Mode
The crank need not be operated for the measurement of voltage. Voltage
applied to the DUT is always displayed when the V/function switch is
set to V.
