2.1
Use for Intended Purpose
•
The multimeter is a portable device which can be held in the
hand during the performance of measurements.
•
Only those types of measurements described in chapter 6
may be performed with the measuring instrument.
•
The measuring instrument, including measurement cables
and plug-on test probes, may only be utilized within the spec-
ified measuring category (see page 53 and the table on
page 5 regarding significance).
•
Overload limits may not be exceeded. See technical data on
page 47 for overload values and overload limits.
•
Measurements may only be performed under the specified
ambient conditions. See page 49 regarding operating tem-
perature range and relative humidity.
•
The measuring instrument may only be used in accordance
with the specified degree of protection (IP code) (see
page 50).
Data Backup
We advise you to regularly transfer your stored data to a PC in
order to prevent potential loss of data in the test instrument.
We assume no responsibility for any data loss.
Battery Pack Safety Precautions
The test instrument is powered by a rechargeable lithium-ion bat-
tery. Consequently, it’s absolutely essential to observe the follow-
ing points:
•
Temperature ranges:
The test instrument with battery pack must
not be exposed to direct
sunlight
or charged, operated or
stored at
high temperatures
, for example in a car.
The following ambient conditions apply to the battery pack:
–
Charging mode (10 ... 45 °C):
The battery may only be charged
within this temperature range.
–
Measuring mode (–10 ... 50 °C):
The battery may only be used
within this temperature range.
–
Storage (–20 ... 50 °C):
The maximum
storage temperature
is
50 °C
.
•
Excessive depletion:
The rechargeable battery’s safety circuit
consumes minimal amounts of current. In order to prevent the
battery from becoming fully depleted, the instrument should
be connected to the mains for recharging at least once a year,
and preferably at more frequent, regular intervals. In some
cases it’s no longer possible to recharge a fully depleted bat-
tery, in which case it must be replaced by GMC-I Service
GmbH.
Attention!
!
Excessive depletion should be avoided because the bat-
tery’s service life might otherwise be reduced, or the bat-
tery could fail. The battery pack is subject to self-
discharging at a rate of roughly 25% per year.
Attention!
!
Battery pack transport:
Observe the supplementary sheet with safety information
for the Z270A or Z270G battery pack with rechargeable
lithium-polymer battery
(3-349-997-15 oder 3-447-030-15)!
The supplementary sheet with safety information for the Z270A/
Z270G battery pack is included with the manufacturer’s safety
data sheet for the installed lithium-polymer battery.
