4.3. DESCRIPTION OF ROTARY SWITCH FUNCTIONS
4.3.1. DC voltage measurement
CAUTION
The maximum input DC voltage is 600Vrms. Do not measure voltages
exceeding the limits given in this manual. Exceeding these limits could
result in electrical shocks to the user and damage to the instrument.
Fig. 2: Use of the clamp for DC voltage measurement
1. Select the position V
Hz%
2. Insert the red cable into input terminal V
CAPHz%Temp and the black cable into
input terminal COM (Fig. 2).
3. Position the test leads in the desired points of the circuit to be measured. The display
shows the value of voltage.
4. If the symbol “O.L” is displayed, this indicates overload status.
5. To use the HOLD and REL functions, please refer to § 4.2.
CAUTION
Due to the high input impedance, it may take some time for the
instrument to zero the display.
The changing value shown on the display with open input terminals is
not to be considered a problem of the instrument and these values
are not added by the instrument while carrying out a real measurement.
