4.3. DESCRIPTION OF MEASURING FUNCTIONS
4.3.1. DC Voltage measurement
CAUTION
The maximum DC which can be applied to inputs is 30V DC. 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. 3: DC voltage measurement
1. Press the MODE key and select the measuring modes MEAS V or MEAS mV. The
message “MEAS” is shown on the display
2. Insert the green cable into input lead mV/V and the black cable into input lead COM
3. Position the green lead and the black lead respectively in the points with positive and
negative potential of the circuit to be measured (see Fig. 3). The value of voltage is
shown on the main display and the percentage value with respect to the full scale on
the secondary display
4. The message “-OL-” indicates that the voltage being measured exceeds the maximum
value measurable by the instrument. The instrument do not perform voltage
measurements with opposite polarity respect to the connection in Fig. 3. The value
“0.000” is shown at display
