Operating Instructions
Thank you for purchasing your AMPROBE
®
multitest
Σ
two-pole voltage tester with LCD screen. The device can be used to
detect DC and AC voltages of between 12 and 690 V, for polarity, phase sequence and throughput testing at up to 500 k
Ω
, and
for FI/RCD tests. The AMPROBE
®
multitest
Σ
carries a high protection rating (IP65), making it suitable for use in harsh
conditions.
Safety Notes: You have selected a device that is designed to offer you a high degree of safety. It conforms to standards DIN
VDE 0682-401 and IEC/EN 61243-3. In order to ensure that the unit is operated correctly and safely, read these operating
instructions thoroughly BEFORE operating the device.
The following safety precautions should be observed:
•
Check the voltage tester for correct functioning immediately before each use (as per VDE specification 0105, part 1),
by connecting it to a known voltage source (e.g. a 230V power socket). If the indicator shows that one or more
functions are not working correctly, do not use the device any further, but have it examined by a qualified service
technician.
•
Always hold the device by its handles. Avoid touching the probe tips.
•
Note that all testing for no voltage should be carried out at two poles.
•
Trouble-free operation is guaranteed at temperatures of between -10°C and +50°C.
•
Keep the device clean and dry at all times. The casing may be cleaned by wiping with a damp cloth.
General points: Voltages have priority. If no voltage is detected at the probe tips (< 3.0V), the device is in throughput testing
mode.
1.) Function:
The device is always activated.
2.) Self testing:
Hold the probe tips together when carrying out this test. The buzzer on the test device should sound clearly and the display
should show "Rx/
Ω
". If the LED screen is blank or dimly illuminated, the batteries must be replaced.
3.) DC voltage testing:
When the probe tips are connected to a DC voltage within the nominal voltage range, the reading is displayed in volts and the
“+” LED indicator lights up. If a negative voltage is detected at probe tip “L1”, a “-” (minus) symbol is displayed.
4.) AC voltage testing:
When the probe tips are connected to an AC voltage within the nominal voltage range, the reading is displayed in volts and the
“+~-” LED indicator lights up.
5.) Phase testing:
Bring one of the probe tips into contact with a conductor, while touching the finger contact located at the back. When a phase
of min. 100V~ is connected, the „Pol/L1“ LED lights on.
6.) Rotatory field testing:
Identify a phase conducting wire as described in point 5. Now connect two phase conductors to the probe tips and touch the
finger contact. If the phase connected to probe tip L2 follows the phase connected to probe tip L1, the phase sequence is right-
handed. The small display indicates “L1”. If this is not the case, there is a left-handed field. The voltage indicator should give a
reading of approx. 400V. If “Pol/L1”appears and the only reading is 230V, only one phase conductor is connected.
7.) Continuity testing:
Bring the probe tips into contact with the conductor, fuse, etc. that is being tested. With resistances of 0-500 k
Ω
the "Rx/
Ω
"
LED lights on and an acoustic signal sounds.
8.) FI/RCD trigger test, PE (zero conductor test):
The AMPROBE
®
multitest
Σ
is equipped with an automatic load, which permits the throughput testing of FI/RCD-safety
switches without triggering. The initial task is to carry out testing between L (phase conductor) and N (zero conductor) (approx.
5s). With immediate connection, L can be tested against PE (earth/ground). The network voltage is indicated. If this is not so,
the FI/RCD safety switch is triggered (max. 30mA).
