Tietzsch Prufball ZAP 350L Bedienungsanleitung Seite 16

4.5 RCD-tripping
The Prüfball ZAP 350L can activate 30 mA RCDs
(residual-current-operated protective device) at
230 V.
Therefore check the voltage between phase and
protective line (earth). Display indicates 230 V.
Press both push-buttons of the Prüfball ZAP 350L,
RCD is activated and display turns off.
4.6 Load test
With the connection of load, also inductive and
capacitive interference voltages are suppressed.
Therefore press both push-buttons.
Symbol at the display indicates the connected
load. A monitoring switches off the load when a
voltage of 260 V is applied.
In case of overheating the integrated thermal pro-
tection switches on. Then an interruption for cooling
is neccessary.
Observe section 2. Safety Precautions, Special
note for load tests!
4.7 Resistance and continuity tests
When the device is switched off hold the test elec-
trodes together in order to perform the continuity
test. „000 Ω" is indicated at the display.
Connect securely both test prods to the test point.
With resistance values between 0 ... 1000 kΩ the LCD
indicates measurement values in "kΩ", in steps of
50 kΩ. With resistance values of more than 1000 kΩ
indication signalises overflow with „OL" and "kΩ".
Note:
The internal energy source is exhausted when the
battery symbol appears during continuity
tests. About 100 test procedures are still possible.
The Prüfball needs to be recharged for 10 hours at a
230 V socket.
Therefore plug the test electrodes into a socket.
The device indicates approx. 230 V and the energy
source is charged. The on-time of 30 seconds is
irrelevant here.
Note:
Maybe that after continuity tests and "oFF" indica-
tion a numerical value is indicated. This value corre-
sponds to the version of the current software.
