OPERATIONS
4.4.1. DC Voltage measurement
CAUTION
The maximum input DC voltage is 1000 V. Do not measure voltages
exceeding the limits given in this manual. Exceeding voltage limits could
result in electrical shocks to the user and damage to the instrument.
Fig. 2: Use of the instrument for DC voltage measurement
1. Select positions
V
or
mV
2. Press the
MODE
key for manually selecting “DC” measurement.
3. Use the
RANGE
key for manually selecting the measuring range (see § 4.2.4) or use
Autorange selection. If voltage value is unknown, select the highest range.
4. Insert the red cable into input lead
HzV
and the black cable into input lead
COM
5. Position the red lead and the black lead respectively in the points with positive and
negative potential of the circuit to be measured (see Fig. 2). The display shows the
value of voltage
6. If the display shows the message “
OL
”, select a higher range.
7. When symbol “
-
” appears on the instrument’s display, it means that voltage has the
opposite direction with respect to the connection in Fig. 2
8. For using the HOLD function see § 4.2.1, for measuring MAX/MIN/AVG values see
§ 4.3.1, for relative measurement see § 4.2.1 and for saving the result see § 4.3.5.
