Important notices for proper indication of phase
- This function can only be used in TT and TN systems!
- Hold the instrument in your hand (palm) in a standard way.
- For correct function of phase indication it is necessary that the test tip is
connected to the phase voltage for at least 2!
- The voltage must be ≥ 190 V / 48 ÷ 52 Hz against the earth, otherwise phase
indication may not work properly!
- Verification of live-circuit shouldn’t be depending on the single-pole phase test
only, but on the voltage measurement (the U function)!
3.4.2. Phase sequence test
This function is intended for testing of phase sequence (rotation).
•
Press and release the
FUNC
key to select the phase sequence test function.
"1 -
" is displayed.
•
Connect the test tips between two phases. "1 - 2 " is displayed.
•
After about 2 seconds, the display shows a moving symbol "1 - 2 _ _ _ 3".
•
Disconnect the test tip on the instrument’s case from second phase
conductor and connect it immediately to third phase conductor. The display
shows the phase sequence "1 - 2 - 3" or "1 - 3 - 2" and the symbol of a
rotating wheel in the direction of the expected phase rotation. Displaying is
finished after about 10 seconds after the test tips are disconnected from the
tested mains.
•
The voltage value is displayed during the test, too.
Important notices for proper indication of phase sequence
- Connect the test tips with tested conductors
thoroughly and steadily
.
- Phase voltage must be 230 ±10% / 48 ÷ 52 Hz.
3.4.3. Function DIGISORT (with DIGIsort optional transmitter only)
The „DIGISORT“ function is intended for distinguishing of up to 12 deenergized
conductors.
•
Choose one conductor as common conductor, for example cable shielding or
protective conductor.
•
Ensure by voltage measurement that all conductors are disconnected from
the power supply!
•
On the opposite end of the bundle of conductors connect the transmitter
DIGIsort. Terminal "GND" connect to dedicated common conductor, terminals
1-12 to other conductors. Turn on the power of DIGIsort.
•
Select on the DIGOHMpro function "DIGISORT" by the
FUNC
key. In the
upper part of the display there is displayed "DIGISORT" and in the lower part
"- - -".
