b Replacing the battery
A 9V compound battery is required to operate the individual measuring instrument. If
the replace battery symbol is displayed approximately 8 hours before the battery
goes dead, it will be necessary to replace the battery. To do this, proceed as follows:
- Switch off the measuring instrument by separating it from the measuring
circuit and disconnect the measuring lines.
- Unscrew the fastening screw of the battery compartment (centre screw at
the rear side of the measuring instrument) by using a suitable screwdriver
(crosshead). It is not necessary to open the device completely for replac-
ing the battery.
- Remove the battery compartment by drawing it slightly. The (used) battery
is secured by a clamp. Use a suitable crosshead screwdriver to remove
this clamp.
- Take out the used battery and replace it by a new one of the same type.
Pay attention to the polarity!
- Fix the clamp till it locks into place and put the battery compartment again
onto the device.
- Now, close the cover carefully. During the replacement make sure that the
battery contact springs in the measuring instrument will not be deformed.
Caution!
Never operate the measuring instrument when it is open! Danger!
Do not leave used batteries in the measuring instrument. Even batteries pro-
tected against leaking may corrode and thus release chemicals that may be
detrimental to your health or they may destroy the battery compartment.
c Replacing the fuses
Always adhere carefully to the safety instructions, if you replace fuses!
Make sure that only fuses of the type stated and of the rated current specified are
used as a replacement. Using repaired fuses or bridging the fuse bracket is not per-
mitted. To replace the fuses disconnect the measuring instrument from the measure-
ment circuit and switch it off. Remove all connected lines, adapters and testing
prods from the measuring device. Use a suitable crosshead screwdriver to open the
housing carefully. First, remove the cover with the battery and then unscrew the last
two recessed head screws. Remove the lower cover part; now the fuses can be
accessed.
Remove the defective fuse(s) and replace it (them) by a fuse (fuses) of the same type
and rated current. For the fuse of the mA-range: 0.4A quick-acting, 600V; common
designation: F0,4A / 600V or F400mA / 600V
For the fuse of the A-range: 10A, quick-acting, 600V; common designation: F10A
LAC 600V.
Caution!
Close and fasten the hosing carefully in reverse order after having completed
the fuse replacement.
Only operate the measuring instrument if the housing is reliably closed and
screwed down.
