FUNCTIONAL CHARACTERISTICS

3.1 Reference conditions

The functional characteristics mentioned in each of the
measurement functions are guaranteed within the following
reference conditions:
- Temperature: +23°C ±3 K.
- Humidity: 45% to 75% relative humidity.
- Supply voltage: 8.5 V ±0.5 V.
- Frequency range of the alternating signal applied: 45 -65 Hz
- Peak factor of the alternating signal applied: √ 2
- Position of the conductor in the clamp jaws: centred.
- Diameter of the conductor: ≤ 5 mm
- No external AC magnetic field
- No electrical field
3.2 Voltage measurements
1. Connect the measurement leads to the instrument's
terminals, complying with the polarities indicated: red lead
on the "+" terminal and black lead on the "COM" terminal.
2. Set the selector switch to the "V " position.
3. Connect the unit to the voltage source to be measured,
making sure if possible that this voltage does not exceed
the maximum acceptable limits (see table below).
Range switching and AC/DC selection is automatic.
If the signal measured is > 45 V peak, the buzzer is activated
if the V-Live function is selected (see § 3.5.2) .

(1) In DC, + OL is indicated on the display when over 600 V
and - OL when over - 600 V.
In AC, OL is indicated on the display over 600 V rms
(2) In AC, if the value of the voltage measured is < 0.15 V,
0.00 is indicated on the display.
For ≥ ≥ ≥ ≥ ≥ 600 V
sound indicates that the voltage measured is higher
than the instrument's guaranteed voltage safety level.
