The Buzzer
Different tones are emitted according to the function given to the buzzer:
- Short and medium sound:
valid key
- Short and high-pitched sound:
prohibited key
- Short and low sound:
Quit MIN/MAX mode
- 2 short and high-pitched beeps:
validation of a configuration parameter
- Short and medium sound every 400 ms:
voltage measured higher than the units guaranteed safety voltage.
- 5 short and medium recurring beeps:
automatic deactivation of the instrument
- Short and medium sound:
measured continuity value, lower than programmed threshold, short-circuit junction
during semi-conductor test.
- Modulated medium continuous sound:
value measured in volts, higher than 45 V peak when the V-Live
function is selected.
3. IMPLEMENTATION FUNCTIONAL CHARACTERISTICS
3.1 Reference conditions
The functional characteristics mentioned in each of the measurement functions are guaranteed in the following
reference ranges:
- Temperature:
+23°C ± 3 K
- Humidity: 45% to 75% relative humidity
- Supply voltage:
8.5 V ± 0.5 V
- Frequency range of applied AC signal: 45 -65 Hz
- Peak factor of applied AC signal:
Ö
2 -
- Position of conductor in clamp jaws: centred
- Conductor diameter: '3d 5 mm -No external AC magnetic field
- No electrical field
3.2 Voltage measurements (V)
1.
Connect the measurement leads to the instruments terminals, complying with the polarities indicated: red lead
on the + terminal and black lead on the
COM
terminal.
2.
Set the rotary switch to position "
V
".
3.
Connect the assembly 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 are
automatic.
Actuate the yellow key to force AC, DC or AC+DC selection manually if necessary.
If the signal measured is > 45 V peak
, the audio indication is activated if the V-Live function is selected
(see § 3.12.9).

600 V AC or DC
(1) In DC, the display indOL above +600 V and -OL above -600 V (900 V in PEAK mode). In AC, the
display indicates OL over 600 Vrms (900 V in PEAK mode).
(2) In AC if the value of the voltage measured is < 0.15 V the display indicates 0.00.
For voltages 600 VDC or rms, a repetitive beep of the buzzer indicates that the measured voltage is
higher than the units guaranteed safety voltage.

MIN/ MAX Mode:
-Accuracy: same as previous table +0.2% L
-Capture time: 100 ms typ.
§
PEAK Mode:
- Accuracy: same as previous table +2% L
- Capture time: 500 µs typ. (2.5 ms max.)

Special characteristics in V-Live mode
- Detection threshold accuracy: 45 Vpeak ± 2V
3.3 Audio continuity test ( )
1. Connect the measurement cables to the unit terminals.
2. Set the rotary switch to position "
3. Connect the unit to the circuit to be tested. The buzzer is continuously active as soon as contact is established
(circuit cl
osed) and if the resistance value measured is lower than the threshold value chosen by the
programming (adjustable from 1 to 40
W
, see § 03.12.10). Above 400
W
, the display indicates
OL
.
