How to prevent automatic TURN-OFF
Switch your meter to "CONTINUOUSLY ON" mode.
Ø
To do this, press y
"ON/OFF"
pushbutton (2) together. The function "CONTINUOUSLY ON"
is shown on the LCD (1) by the symbol
ellow multi-function pushbutton (5) and the
(8).
ON
Automatic TURN - OFF
The meter turns off automatically, when the measured value remains constant
(variations of the measured value < + 2digits) for about 10 minutes and when
neither a pushbutton nor the function selector switch is operated during that
time.
Note:
Electric discharges and high-frequency interference may cause incorrect
information to be displayed and block the measuring process. Reset the meter
by switching it OFF and ON again otherwise, check the battery connections.
Disconnect the meter from the measuring circuit before you open it, and see
section "16.Maintenance"!
Repair, replacement of parts and calibration
When opening the meter, live parts may be exposed. Therefore, the meter
must be disconnected from the measuring circuit prior to opening its case
for repair or replacement of parts. If repair cannot be avoided unless the
meter is opened and live, this work must only be performed by a qualified
person who understands the danger involved.
Fausts and extraordinary stress
When it must be assumed that the safe operation is no longer possible,
take the meter out of service and secure it against accidental use.
It is assumed that safe operation may not be possible,
l
when the meter shows obvious signs of damage,
l
when the meter no longer functions correctly,
l
after prolonged storage under adverse conditions,
l
due to severe stress during transportation.
2. Switching the meter "ON”
Battery
Fit the
meter with a 9V flat cell battery provided along with the meter.
Before you use the meter for the first time or after storage, refer to Section
"16.1 Maintenance-Battery".
Switching the meter "ON”
Ø
Press the "ON/OFF" pushbutton (2).

Caution
Disconnect the meter from the measuring circuit before you open it to replace the
battery or the fuse!
16.1. Battery
Prior to initial start-up, or after storage of meter, verify that the batteries of
does not leak. Repeat this check in regular short intervals. If the battery leaks,
completely remove the battery electrolyte carefully with a moist cloth and install a
new battery before you operate
again.
When the symbol " " (17) appears on the LCD (1) replace the battery as soon
as possible. You can continue to measure, but a reduced measuring accuracy
must be taken into account.
The meter operates with 9V flat cell battery according to IEC 6 F 22 or IEC6 Lr61 or
with a suitable NiCd storage battery.

part of the case are fixed together at the top on the front by means of wedges.
Ø
Remove the battery from the compartment and carefully disconnect the
contacts from the battery.
Ø
Snap the connection contacts to a new 9V battery and insert the battery in to
the battery compartment.
Ø
Replace the lower part of the case. Start at the top on the front and take care
that the detent hooks are properly engaged at this point.
Ø
Tighten the lower part with the two screws.
Ø
Please destroy the batteries in an environment friendly way.
16.2 Fuses
A blown fuse is signalled on the LCD display the instant a measured quantity
having a voltage of more than 4 V is applied to the corresponding connection
sockets. Then, the digital display (9) shows "FUSE".
The 16 A fuse all other current measuring ranges. All other measuring ranges
continue to function. When a fuse blows, first eliminate the cause of the overload
using the meter again !
