5.1.2 Recharging the Batteries

Attention!

Use only the charger (Z507A) which is offered as an op-

tional accessory for this instrument to charge the batter-

ies inserted in the instrument.

Make sure that the following conditions have been fulfilled be-

fore connecting the charger to the charging socket:

– rechargeable batteries have been inserted with correct

polarity, no normal batteries

– The test instrument has been disconnected from the

measuring circuit at all poles

– The instrument must remain off during charging.

Recharging of the batteries begins as soon as the charger is con-

nected to the mains and to the charging socket (see figure 2.1).

Charging takes approximately 5 hours and 30 minutes (integrated

safety timer) if the batteries have been fully depleted.

Safety Precautions

• Do not attempt to recharge alkaline batteries: they may leak,

explode etc. The test instrument may be severely damaged or

destroyed as a result.

• After initially charging new batteries and after rechargeable

batteries have not been used for a lengthy period of time (sev-

eral months), operating hours after charging may be signifi-

cantly less than usual. If this is the case, repeat the charging

procedure several times.

Autonomous, intelligent charging stations execute charging/

discharging cycles of this sort automatically (see instructions

included with the charging station). This procedure increases

the capacity of the batteries, thus making longer periods of

operation possible between charging cycles.

• If no improvement is achieved in this way, one or more of the

rechargeable batteries may no longer fulfill the original specifi-

cations. If this is the case, the defective rechargeable battery

should be identified, e.g. with the help of the voltage measure-

ment, and replaced.

• Battery capacity is gradually reduced as a result of long and

frequent use. When you notice that this is the case, all of the

rechargeable batteries should be replaced.

5.2 Cleaning

Use a soft cloth and soapy water for cleaning. Do not place the

test instrument back into service until its surface is completely dry.

Attention!

Do not use cleaning agents which contain benzine or al-

cohol! Prevent liquids from penetrating into the test in-

strument’s interior.

5.3 Recalibration

The measuring tasks performed with your instrument, and the

stressing it’s subjected to, influence aging of its components and

may result in deviation from the specified levels of accuracy.

In the case of strict measuring accuracy requirements, as well as

in the event of use at construction sites with frequent stress due

to transport and considerable temperature fluctuation, we recom-

mend a relatively short calibration interval of once per year. If your

instrument is used primarily in the laboratory and indoors without

considerable climatic or mechanical stressing, a calibration inter-

val of once every 2 to 3 years is sufficient as a rule.

During recalibration at an accredited calibration laboratory

(DIN EN ISO/IEC 17025), deviations from traceable standards

demonstrated by your measuring instrument are documented.

Ascertained deviations are used to correct display values during

later use of the instrument.

We would be happy to perform DAkkS or factory calibration for

you at our calibration laboratory. Further information is available at

our website:

www.gossenmetrawatt.com ( Company  DAkkS Calibration

Center or  FAQs  General – Calibration Questions and

Answers).

Recalibration of your instrument at regular intervals is essential for

the fulfillment of requirements according to quality management

systems per DIN EN ISO 9001.

* Examination of the specification, as well as adjustment, are not included

in calibration. However, in the case of our own products, any required

adjustment is performed and adherence to the specification is con-

firmed.
