Rotating Field Test (Max. 400 V); One-Hand Test; Lighting Of The Measurement Location; Continuity Test - Testboy Profi III LED Operating Instructions Manual

Operation

Rotating field test (max. 400 V)

Protective clothing and insulation locations can impair the function.
Hold the complete area of the handles L1 and L2
Place the tip of the probes L1 and L2 on two external conductors (phases)
and check to see whether the external conductor voltage of, e.g. 400 V is
applied.
A clockwise sequence (phase L1 before phase L2) is present if the "R" LED
illuminates.
An anticlockwise sequence (phase L2 before phase L1) is present if the
"L" LED illuminates.
Determination of the phase sequence must always be carried out with the
probes transposed. Thereby, the phase sequence must change
Note:
The phase sequence test is possible in earthed AC voltage mains supply
from 200 V, 50/60 Hz (phase to phase).

One-hand test

Locking both hand parts is possible by the distance piece on the measure-
ment line. The distance of the measurement probes can be adjusted by sim-
ply rotating. ( Schuko/CEE)

Lighting of the measurement location

Lighting of the measurement locations is switched on and off by activating
the L.H button.

Continuity test

(To switch on, place the test probes on one another)
Place the test probes on the line to test, fuse or similar. For a resistance of
0 - 50 k, the green "Rx/" LED illuminates and an acoustic signal sounds.
