Safety Information
T his Me er compliest with EN 61010-1:2010 fety sa measurement
requirement:Pollution Degree 2, measurement
category CAT III 600V and Double Insulation.
CAT II (measurement category): Test and measuring
circuits connected directly to utilization points (socket outlets
and similar points) of the low-voltage MAINS installation.
Use the Meter only as specified in this operating manual,
otherwise the protection provided by the Meter may be
impaired.
Danger identifies conditions and actions that pos e
hazard(s) to the user.
Warning alerts users to avoid electric shock.
Caution identifies conditions and actions that ma y
damage the Meter and affect accurate
measurement.

sa rma care refety info tion full foy be us oring
servicing the instrument.
Do not apply more than 600V.
Do not use the Meter around explosive gas,
vapor or dust.
Do not use the Meter in a wet environment.
When using the test leads, keep your figure s
away from the lead contacts. Keep your
figures behind the finger guards on the leads .
Do t u the th any p or co rno se Meter wi arts ve
removed.
Operating Caution identifies conditions that user
needs to t ake ex rat care during opera ting the Meter
Warning
Do not use the Meter if it is damaged or metal
part is exposed. Look for cracks or missing
plastic.
Be careful when working above 33V rms, 46.7 V
ac rms or 70V DC. Such voltages pose a shock
hazard.
Discharge all loading of circuit under test afte r
measuring high voltage.
When carrying out insulation measurement,
do not contact the circuit under test.
Caution
When performing resistance tests, remove all
power from the circuit to be measured and
discharge all the power.
Wh ing then icserv e Meter, u y se onl only the
test leads and power adaptor with the same
model number or identical electrical
specifications.
Do not use the Meter if the battery indicator
( ) a shows battery empty condition. Take
the battery out from the Meter if it is not use d
for a long time.
Do not use or store the Meter in an
environment of high temperature, humidity,
explosive, inflammable and strong magnetic
field. The performance of the Meter may
deteriorate after dampened.
So c th a m dft lo nd ild etergent s be u dhould se
to clean the surface of the Meter when
servicing. No abrasive and solvent should be
u d to p nt the su of the omse reve rface Meter fr
corrosion, damage and accident.
Dry the Meter before storing if it is wet.

International Electrical Symbols
International symbols on the Meter and in this manual
are explained in Table 2.
Table 2. International Electrical Symbols
Battery Saver (Sleep Mode)
The Meter enters the Sleep Mode and blanks the displa y
if there is no button press for 15 minutes. This is don e
to conserve battery powe The Meter comes out r. of

for 1 second.
Battery Indication
There is a battery indicator shown on the upper left corner
of the display. Please refer to Table 3 for detailed
explanation.
Battery Voltage
5.9V ~ 10.6V. It means the battery is
empty, Do not use the Meter as it
cannot
guarantee accuracy.
10.7V ~ 11.1V. It means the battery is
almost empty, replacing battery is
necessary. At this status, the Meter can
still output 500V and 1000V to measure,
the measured accuracy will not be
affected.
11.2V ~ 12.2V
12.2V or more

Operating Cautio n
When performing insulation resistance tests,
remove all power from the circuit to be
measured and discharge all the power.
Operating the Meter must be very careful as it
outputs dangerous voltage during
measurement. Must make sure the tested object
is firmed clipped, hands are away from the
clips, then press TEST button to output high
voltage.
Do not short circuit the testing leads during
high voltages output or test insulation
resistance after high voltages output. This kind
of in correc erat op ting may ca se u sp andarking
fire, which damages the Meter and cause
personal injury.
Do not measure over 10 seconds when:
measuring resistance ＜2MΩ with use of 500V.
measuring resistance ＜5MΩ with use of 1000V.
measuring resistance ＜8MΩ with use of 1500V.
measuring resistance ＜10MΩ with use of 2500V.
To measure insulation resistance, set up the Meter as
Figure 5 and do the following:
Press button to select insulation resistanceIR
measurement.
When there is no testing voltage output, press
and button to select 500V, 1000V, 2500V
or 5000V voltage range.
W hen pe ingrf rmo in ulas tion resistance tests, remove
all power from the circuit to be measured and
discharge all the power.
Insert the red test lead into two terminals, the LINE
black one into and the green one into GUARD EARTH.
Connect the red and green alligator clip to the circui t
to be measured, negative voltage outputs from LINE
terminal.

Using Power Adaptor
Refer to Figure 6 for the use of power adaptor.
Figure 6. Using Power Adaptor
Open the side safey shutte r, then you will see ther e
is a power adaptor input terminal.
Make sure the Meter is power off and Insert the
UT512 power adaptor to the input terminal.
It is highly recommended to take out all the batteries
when you are using the power adaptor.
Make sure the Meter is power off when you
disconnect the UT512 power adaptor from the Meter.
It is highly recommended to use Uni-Trend supplied
UT512 power adaptor to avoid unnecessary danger.
