Safety in use
• Use the instrument in accordance with the manual, otherwise the instrument
•
•
•
•
•
•
•
may be dangerous for the operator!
Read this instruction manual carefully, otherwise use of the instrument may be
dangerous for the operator, for the instrument or for equipment under test!
Use only grounded mains outlets to supply the instrument!
Do not use any damaged mains outlet or damaged mains connection cable!
A competent authorized person must only carry out Service or calibration
procedure!
Only a skilled person, who is familiar with hazardous voltage operations, can
handle CE MultiTester!
Disconnect all unused test leads before starting measurement; otherwise the
instrument can be damaged!
In case of failure of the instrument test results may be impaired. It is a good
practice to regularly confirm/check the accuracy of the tester (by simple field
calibration, comparison to known reference values etc).

1.2 Warranty
Unless stated differently, our instruments are guaranteed against any manufacturing
or material defect. They do not bear the specification known as the safety
specification. Our guarantee, which may not under any circumstances exceed the
amount of the invoiced price, is for the repair of our faulty equipment only, carriage
paid to our workshops. It is applicable for normal use of our instruments and does not

apply to any damage or destruction caused, notably by error in mounting, mechanical
accident, faulty maintenance, defective use, overload or excess voltage.
Our responsibility is strictly limited to the pure and simple replacement of the faulty
parts of our equipment; the buyer expressly renounces any attempt to find u s
responsible for damages or losses caused directly or indirectly.Our guarantee is
applicable for twelve (12) months after the date at which the equipment is made
available. The repair, modification or replacement of a part during the guarantee
period will not result in this guarantee being extended.

4.1. Withstanding test:
Warning !
•
•
•
•
•
•
•
Disconnect all unused test leads before starting measurement; otherwise
the instrument can be damaged!
Only a skilled person, who is familiar with hazardous voltage operations, can
perform this measurement!
Check instrument and test leads for any sign of damage or abnormality
before connecting them to the instrument. DO NOT use test probes in case
of any damage or abnormality!
Always handle the instrument and connected accessories as the
Withstanding test sockets and leads are under the hazardous voltage!
Never touch exposed probe tip, connected equipment under test, or any
other energized part during the measurements. Make sure that NOBODY
else can contact them either!
Connect test probes only for withstanding measurement, and disconnect
them immediately after the test!
DO NOT touch any part of test probe in front of the barrier (keep your fingers
behind the finger guards on of the probe) – possible danger of electric
shock!
Always set the lowest possible trip-out current.

How to carry out the measurement
STEP 1.
Set rotary switch to HV (high voltage) position. The following heading
is displayed:
Function name
Tripping out current
Nominal test voltage
Leakage current
(main result)
Character of selected part of leakage current
Selected (resistive or capacitive)
part of leakage current
Set timer value
Test voltage
Timer key to set timer
value or to switch it on/off
Un key to select
nominal test voltage
Burn key to set burn mode
Ilim key to select tripping out
current or to select character
of displayed leakage current

Select test parameters as follows:
Test voltage
-
Use U N key to select appropriate test voltage that can be set using ↑ ↓ keys
from 100 V to 1000 V in 10 V steps and from 1000 V to 5000 V in 50 V steps.

Trip-out current / character of displayed part of leakage current
-
Press Ilim key in order to reach menu for trip-out current selection and
character of displayed part of leakage current (resistive or capacitive). See the
following figure.

Fig. 6. Trip-out current selection menu
-
Use ↑ and ↓ keys to select appropriate trip-out current.
Press Chr I in order to change the character of displayed part of leakage
current. If the selected part is resistive,
sign is displayed behind mA unit.
For capacitive part
sign is displayed behind mA unit.
Press Exit key to exit Trip-out current selection menu.
NOTE !
The set thresholdLimit value of test current is always compared with the absolute
value of test current.
