7 Operation
Attention!
!
The protective foil on the two sensor surfaces (finger
contacts) of the test plug must be removed to ensure re-
liable detection of touch voltages.
7.1 Power Supply
The instrument is powered by rechargeable batteries. The
included Master Battery Pack (Z502H) or commercially available
individual rechargeable or regular batteries can be used.
Note
If at all possible use the included battery pack (Z502H)
with sealed cells. This ensures that the complete set of
rechargeable batteries is always replaced at the same
time and that all batteries are inserted with correct polar-
ity, in order to assure that they do not fail.
The included Z502H battery pack has already been inserted
during initial startup (see condensed operating instructions).
7.1.1 Inserting or Replacing the Battery Pack (Z502H) or Com-
mercially Available Individual (Rechargeable) Batteries
Attention!
!
Before opening the battery compartment, disconnect the
instrument from the measuring circuit (mains) at all poles!
Attention!
!
Commercially available, individual rechargeable or regu-
lar batteries must comply with the technical data (see
page 10).
➭ Loosen the slotted screw for the rechargeable battery com-
partment lid on the back and remove the lid.
➭ Remove the depleted battery pack or commercially available
rechargeable or regular batteries.
➭ Insert the battery pack or commercially available rechargeable
or regular batteries into the battery compartment.
Attention!
!
In the case of commercially available, individual re-
chargeable or regular batteries: make sure that all of the
batteries are inserted with correct polarity. If just one bat-
tery is inserted with reversed polarity, it will not be recog-
nized by the instrument and may result in leakage from
the batteries and damage to the instrument.
➭ Replace the lid and retighten the screw.
Note
Dispose of the battery pack or commercially available,
individual rechargeable or regular batteries in an environ-
mentally sound fashion when their service life has nearly
expired (approx. 80% charging capacity). See section 24,
“Disposal and Environmental Protection”, on page 99.
7.1.2 Charging the Battery Pack (Z502H) in the Tester
Attention!
!
If commercially available, individual rechargeable batter-
ies are used, they must be charged externally. Do not
use the Z502R charger to charge commercially available
individual batteries. The quality of commercially available,
individual rechargeable batteries cannot be checked and
may result in overheating and thus deformation and ex-
plosion when charging them in the instrument.
Attention!
!
If commercially available, individual rechargeable batter-
ies are used, they must be charged externally. Do not
use the Z502R charger to charge commercially available
individual batteries.
The quality of commercially available, individual re-
chargeable batteries cannot be checked and may result
in overheating and thus deformation and explosion when
charging them in the instrument.
Attention!
!
Regular batteries may not be charged.
Attention!
!
Use only the Z502R charger in order to recharge the
Compact Battery Pack (Z502H) in the test instrument.
Attention!
!
The Z502R charger is suitable for mains operation only!
Attention!
!
Do not switch the test instrument on during charging.
The charging process may otherwise be impaired.
➭ Verify that the battery pack (Z502H) is inserted, i.e. that com-
mercially available battery packs or batteries are not inserted.
➭ Insert the correct mains plug for your country into the charger
Z502R.
➭ Connect the Z502R charger to the test instrument with the
jack plug, and then to the 230 V mains with the interchange-
able plug.
➭ Do not disconnect the charger from the test instrument until
the green LED (charged/ready) lights up.
If the rechargeable batteries or battery pack have not been used
or recharged for a lengthy period of time (> 1 month), thus result-
ing in excessive depletion:
Observe the charging sequence (indicated by LEDs at the char-
ger) and initiate a second charging sequence if necessary (dis-
connect the charger from the mains and from the test instrument
to this end, and then reconnect it).
Please note that the system clock stops in this case and must be
set to the correct time after the instrument has been restarted.
7.2 Switching the Instrument On/Off
The test instrument is switched on by pressing the ON/START▼
key. The menu which corresponds to the momentary selector
switch position is displayed.
The instrument can be switched off manually by simultaneously
pressing the MEM and HELP keys.
After the period of time selected in the SETUP menu has elapsed,
the instrument is switched off automatically (see “Device Set-
tings”, section 8).
Battery Test
A battery test is performed after switching the instrument on.
If supply voltage has fallen below the permissible
lower limit, the pictograph shown at the right appears.
“Low Batt!!!” is also displayed along with an icon.
The instrument does not function if the batteries have been
depleted excessively, and no display appears.
Ensure adequate power supply by charging the rechargeable bat-
tery pack (Z502H/) or by inserting fully charged, commercially
available rechargeable batteries or new batteries. See section 7.1,
“Power Supply”, on page 26.
