Clamp Multimeter METRACLIP 86
English
Step 2: determination of a "measurement" period:
Within the next 10 seconds, apply the test probe to the presumed L3
phase. The "MEAS" indication then blinks on the display unit as soon as
the L2 phase is disconnected; the device is in the calculation phase.
Remark:
if the measurement period has not been determined, the device emits a
beep and displays the "Err Hz" or "ErrV" message, then "rdy". Repeat the
procedure from 4.
Result: when the order of the phases has been determined, the device emits a
beep and the indication of order of the phases is displayed on the screen, as
follows:
0.1.2.3 when the direction of rotation is direct. The "0" symbol blinks and
turns clockwise;
0.3.2.1 when the direction of rotation is reversed. The "0" symbol blinks
and turns anticlockwise.
Remark:
if the order of the phases has not been determined, the device emits a
beep and displays the "Err" message. Repeat the procedure from 4.
3.13 FREQUENCY MEASUREMENT (HZ)
The frequency measurement is available in
V, W
and
A
for AC and AC+DC
quantities. The measurement is based on a count of the passages of the signal
through zero (positive-going edges).
3.13.1 Frequency measurement in voltage
To measure the frequency in voltage, proceed as follows:
1.
Set the switch to
and press the
key. The Hz symbol is
displayed.
2.
Select AC or AC+DC by pressing the yellow
key until the desired
choice is reached.
3.
Connect the black lead to the
COM
terminal and the red lead to “
+
”.
4.
Place the test probes or the crocodile clips on the terminals of the
circuit to be measured.
