5.3. AC/DC VOLTAGE MEASUREMENT WITH LOW IMPEDANCE (LOZ)
CAUTION
The maximum input AC/DC voltage is 600V. 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. 4: Use of the instrument for AC/DC voltage measurement with low impedance (LoZ)
1. Select position LoZV . The “LOZ” symbol is shown
2. Press the MODE key to select possibly the “AC” or “DC” measurement
3. Insert the red cable into input terminal
Hz%V
and the black cable into input
terminal COM
4. Position the red lead and the black lead respectively in the desired spots of the circuit
to be measured (see Fig. 4) or in the spots with positive and negative potential of the
circuit to be measured (see Fig. 2). The display shows the value of voltage.
5. The message
“OL.” indicates that the value of DC voltage exceeds the maximum
measurable value.
6. When symbol
“-” appears on the instrument’s display, it means that voltage has the
opposite direction with respect to the connection in Fig. 2
7. To use the HOLD, RANGE and REL functions, see § 4.2
