1 Safety
MIC-2505 meter is designed for performing check tests of protection against electric shock
in mains systems. The meter is used for making measurements and providing results to determine
safety of electrical installations. Therefore, in order to provide conditions for correct operation and the
correctness of the obtained results, the following recommendations must be observed:
•
Before you proceed to operate the meter, acquaint yourself thoroughly with the present manual
and observe the safety regulations and specifications determined by the producer.
•
Any application that differs from those specified in the present manual may result in a damage to
the device and constitute a source of danger for the user.
•
MIC-2505 meters must be operated only by appropriately qualified personnel with relevant certifi-
cates authorising the personnel to perform works on electric systems. Operating the meter by un-
authorised personnel may result in damage to the device and constitute a source of danger for the
user.
•
During measurements of insulation resistance, dangerous voltage up to 2.5 kV occurs at the ends
of test leads of the meter.
•
Before the measurement of insulation resistance you must be sure that tested object is discon-
nected from the power supply.
•
During the measurement of insulation resistance do not disconnect test leads from the tested ob-
ject before the measurement is completed (see par. 3.1); otherwise the capacitance of the object
will not be discharged, creating the risk of electric shock.
•
The instrument must not be used for the mains and equipment in rooms with special conditions,
such as fire or explosion hazard.
•
It is unacceptable to operate the following:
⇒
a damaged meter which is completely or partially out of order,
⇒
a meter with damaged test leads insulation,
⇒
a meter stored for an excessive period of time in disadvantageous conditions (e.g. excessive
humidity). If the meter has been transferred from a cool to a warm environment with a high
level of relative humidity, do not start measurements until the meter is warmed up to the am-
bient temperature (approximately 30 minutes).
•
Displayed
BATT
symbol indicates insufficient voltage of power supply and the need to charge the
accumulator or replace batteries.
•
Symbols
Err
X
, where
X
is a number 1…9, indicate incorrect operation of the meter. If after restart-
ing the device this situation is repeated - it indicates that the meter is damaged.
•
If after switching ON and displaying software version, message
is displayed and the meter
switches OFF - send the meter for servicing. When
is displayed every time after the meter is
switched ON, but the meter enters the measurement mode – update its software.
•
Before measurement, choose a correct measurement function and make sure that test leads are
connected to respective measuring terminals.
•
Do not operate a meter with an open or incorrectly closed battery (accumulator) compartment or
power it from other sources than those specified in the present manual.
•
R
ISO
inputs are electronically protected against overloads (caused by e.g. connecting the meter to
a live circuit) up to 600 V for 60 sec.
•
Repairs may be carried out only by an authorised service point.
Note:
Due to continuous development of the meter’s software, the actual appearance of the display,
in case of some of the functions, may slightly differ from the display presented in this operat-
ing manual.
