1. General presentation
1.2. Warnings and notes
In order to reach high level of operator’s safety while carrying out various tests and
measurements using CE Multitester, as well as to keep the test equipment undamaged,
it is necessary to consider the following general warnings:
If the test equipment is used in a manner not specified in this user manual the
protection provided by the equipment might be impaired!
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).
Meaning of , signs on front panel:
Insulation section
Dangerous voltage may be present; measurements
shall be carried out only on de-energized object
Continuity section
Measurements shall be carried out only on de-
energized object. Read instructions on how to
replace blown-up fuse.
Withstanding section
Dangerous voltage may be present. Switch off the
instrument immediately if the red warning lamp (fig.
1., pos. 12) does not light after switching on HV
generator, and service the instrument. Always
handle as the test leads are energized.

MI 2094 CE MultiTester General presentation

Function test section
Dangerous voltage is present on the TEST
SOCKET (fig.1, pos.10) after pressing the
START/STOP push button.
Power supply input
Dangerous voltage is present on the fuses. Switch
off the instrument and disconnect all test cables
and mains cord before replacing the fuses or
opening the instrument.
Notes!
For correct operation of the instrument fuses F3 and F4 must be in good
condition because the test socket is the point from which the instrument
observes the input voltage (zero crossing for soft start of internal generator).
The CE Multitester enables connection to supply
systems other than TN or TT types. For this
reason earth control can be disabled (see chapter
5.5. System configuration). With the disabled
earth control, the instrument warns each time
when it is powered on with the message.
Note that the instrument must be properly
grounded.
1.3. 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 us responsible for
damages or losses caused directly or indirectly.

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 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:
Fig. 4. Main menu in HV function
STEP 2.Select test parameters as follows:
Test voltage
- Use UNkey 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.

- Press Exit key to exit Test voltage selection menu.
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 Limit value of test current is always compared with the absolute value of
test current.
