OPERATING INSTRUCTIONS

4.4.1. DC, AC+DC Voltage measurement

The maximum input DC voltage is 1000V. 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. 22: Use of the instrument for DC voltage measurement
1. Select positions V
2. Insert the red cable into input terminal VHz%CAPTemp
input terminal COM.
3. Position the red lead and the black lead respectively in the spots with positive and
negative potential of the circuit to be measured (see Fig. 22). The display shows the
value of voltage.
4. If the display shows the message "O.L", select a higher range.
5. When symbol "-" appears on the instrument
opposite direction with respect to the connection in Fig. 22.
6. To use the HOLD, RANGE and REL function, see § 4.2.
7. For AC+DC measurement, see § 4.3.2 and to use the internal functions, see § 4.3.
