9. Maintenance
Remove test leads and turn the power off before opening the
01! Dangerous voltage!
Any work to be carried out on an opened 01 under voltage is
strictly reserved for qualified electrotechnical personnel who must take special
precautionary measures to avoid accidents.
This is how to ensure that the 01 is free from any voltage before
the instrument is opened:
- first remove the safety test leads from measured object.
- then remove both safety test leads from the 01.
- turn the rotary switch to the "OFF" position.
9.1 Instrument safe-guarding
In certain circumstances, safety during the use of the 01 can no
longer be guaranteed; when for instance:
- there is visible damage to the housing
- measurement errors occur
- the instrument has been subjected to prolonged storage under unfavorable
conditions and
- the instrument has been subjected to severe transport stresses.
In such cases the 01must be immediately switched off, removed
from the measurement points and secured against any future unintentional
operation.
9.2 Cleaning
Wipe the case of the 01 with a clean dry cloth (exception: spe-
cial cleaning cloths). Do not use any solvents and/or abrasives to clean the
01.
9.3 Battery replacement
Remove test leads and turn the power off before opening the
01! Dangerous voltage!
The 01 is powered by a 9 V block battery. Battery replacement
(see figure 11 below) becomes necessary when the low battery indicator shows
in the display .
This is how to change the battery:
- Remove the safety test leads from the measured circuit.
- Remove the safety test leads from the 01.
- Turn the rotary switch to the "OFF" position.
- Remove the protective rubber holster from the 01.
- Place the01 on its front side and remove the three screws
from the case back.
- Lift the end of the case back near the input terminals until it gently unsnaps
from the case front at the end nearest to the LCD display .
- Remove the empty battery from inside the case front and carefully discon-
nect it from the battery connector leads.
- Snap the battery connector leads to the terminals of a new battery and
reinsert the battery into the case front. Ensure that the battery leads do not
become pinched between the case back and case front.
- Press the case back and case front together again and reinstall the three
screws.
- Place the 01 back into its protective rubber holster .

- Turn the rotary switch to the "OFF" position.
- Remove the protective rubber holster from the 01.
- Place the 01on its front side and remove the three screws
from the case back.
- Lift the end of the case back near the input terminals until it gently unsnaps
from the case front at the end nearest to the LCD display .
Do not remove any screws from the printed circuit board of the
01!
- Lift the printed circuit board from the front case.
- Gently pry one end of the defective fuse loose from the fuse holder.
- Then slide the defective fuse completely out of the fuse holder.
- Install a new fuse of the same rating, fast acting characteristic and size.
- Make sure the new fuse is centered in the fuse holder.
- Replace the printed circuit board into the case front.
- Ensure that the battery leads do not become pinched between the case
back and case front.

10. How to use the protective rubber holster
- The safety test leads can be stored by wrapping them around the protec-
tive rubber holster and then clipping the probes into the protective probe
holders on the rear of the holster (see figure 13).
- A safety test lead can be clipped into the probe holder on the protective
rubber holster with the test probe protruding, in order to apply the probe
together with the 01 to a measuring point .
- The rear tilt stand on the protective rubber holster allows the
01 to be placed standing upright (for easier display reading)
or hung up (see figure 14).
- The protective rubber holster can also be hung on a nail if so desired.
