must appear within 10 seconds. The optical test output for active
energy consumption is no longer permanently "lit".
Procedure:
1. Apply a load current of 0.1% of the basic current I
5 A) and the voltage U
meter must remain in no-load.
2. Increase the load current to 0.4% I
energy direction arrow "Q" must appear within 10 seconds. The optical
test output for active energy consumption is no longer permanently "lit".
If the meter is provided with a battery, this must be changed if one of the
following events occurs:

The symbol appears on the display.

The battery has been in the meter for more than 10 years (preventive
servicing). It is recommended to note the date of insertion on the
battery. The 10 years depend on the product and on the age of the
battery when inserting it into the meter.

The battery operating hours counter indicates over 80,000 hours (can
be read under code C.6.0 in service mode).

The battery charge indicates less than 4.8 V (can be read under code
C.6.1 in service mode).
Meters with or without battery
Only meters parameterised as "fitted with battery" have the
and the battery operating hours counter.
Dangerous voltage on contacts in the battery compartment
The contacts in the battery compartment may have mains voltage applied.
Therefore only remove the battery with the existing battery holder and
insert the new battery only with the battery holder. Ensure that the contacts
are never touched.
Replacement battery
As a replacement, use only a lithium battery with a rated voltage of 6 V and
the same construction as the original battery.
Procedure:
1. Remove the front door seal.
2. Open the front door.
The battery compartment is on the left below the liquid crystal display.
