Phase test

- With the rotating switch 9 , select the desired function (VoltSense) on the
ZA-TEC ZA 6-2.
- Press the blue key 4 to switch over to Hi (high sensitivity) or Lo (low sensi-
tivity).
- Connect the red safety measuring lead to the jack J for V of the
ZA-TEC ZA 6-2.
- Bring the safety measuring lead into contact with the measuring point of the
system part.

Maintenance


Before opening the ZA-TEC ZA 6-2, ensure that it is not
connected to a source of voltage! Electrical hazard!
Any work required on the ZA-TEC ZA 6-2 when it is under voltage must be done
only by a qualified electrician. Special steps must be taken to prevent accidents.
Before opening the ZA-TEC ZA 6-2, remove it from all sources of voltage as follows:
- First remove both safety measuring leads from the measurement points.
- Remove both safety measuring leads from the ZA-TEC ZA 6-2
- Turn the rotating switch  to "OFF".

9.1 Securing the unit

Under certain circumstances, the safety of the ZA-TEC ZA 6-2 can no longer be
guaranteed. This may be the case if:
- there are visible signs of damage on the unit,
- errors occur in measurements,
- the unit has been stored for a long period of time under the wrong conditions, and
- if the unit has been subjected to rough handling during transport.
In these cases, the ZA-TEC ZA 6-2 must be switched off immediately, removed from
the measuring points and secured to prevent it from being used again.
9.2 Cleaning
Clean the outside of the unit with a clean dry cloth. (Exception: any type of
special cleaning cloth). Never use solvents or abrasives to clean the testing unit.
Ensure that the battery compartment and the battery contacts have not been
contaminated by electrolyte leakage.
If any electrolyte or white deposits are seen near to the battery or in the battery
compartment, remove them with a dry cloth, too.

9.3 Battery replacement


Before opening the ZA-TEC ZA 6-2, ensure that it is not
connected to a source of voltage! Electrical hazard!
The ZA-TEC ZA 6-2 is supplied by means of one 9 V block battery. Battery
replacement (see figure 12) is required as soon as all segments of the battery
symbol 3 have disappeared and the battery symbol is flashing.
To replace the battery, proceed as follows:
- First remove the safety measuring leads from the measurement circuit.
- Remove the safety measuring leads from the ZA-TEC ZA 6-2.
- Turn the rotating switch  to "OFF".
- Remove the protective rubber holster M from the ZA-TEC ZA 6-2.
- Lay the ZA-TEC ZA 6-2 on its front and loosen the screw from the cover of
the battery compartment.
- Lift off the battery compartment cover from the bottom part of the battery
compartment.
- Lift the discharged battery out of the battery compartment and remove the
battery leads carefully from the battery.
- Connect the new battery with the battery leads and arrange them in such a
way that they are not crushed between the two halves of the housing. Then
place the battery in the correct position in the battery compartment.
- Clip the battery cover onto the bottom part and tighten the screws.
- Replace the ZA-TEC ZA 6-2 in its protective rubber holster M .
