?Once you start the tester, it waits for your selection. You can go up and down in voltage to select the voltage at which you want to
test the insulation. Once you have selected that voltage, you need to connect the test leads to the Insulation Tester to measure.
Then it measures voltage to ensure there is no voltage present on the equipment under test. If there is a voltage present,
it will warn you to disconnect the circuit before proceeding. If it’s free of any voltage, then you can proceed with the testing.
This ensures that no damage is done to the Insulation Tester KM 6213AIN.

SAFETY RULES
RISK OF ELECTRIC
SHOCK
Follow the instructions in the Manual for every measurement. Read and
understand the general instructions before attempting to use this tester.
READ THE MANUAL
When using the tester with test leads, ensure that they are safe and
properly authorized.
Disconnect the tester from any external circuit when checking or changing
the Fuse and / or batteries.
!
CAUTION
When working near high tension systems rubber gloves and shoes
should be worn.
Work on clean, dry crushed rock or an insulating blanket.
Avoid bare hand to hand contact between the tester and extended test leads.
While the probability of the occurrence of one of these events is low,
personnel safety will, nevertheless, be enhanced by the following :
Preparations for testing of power system grounding or close to it can leave
personnel vulnerable to exposure caused by faults at or fed from the system
under test, transferred potentials from remote test grounds, and inadvertent
line energizations. Always insulate the device under test.
Do not carry out field measurements on either the power system grounding,
during periods of forecast lightning activity, or any non insulated system or
non insulated circuit. In the event that lightning occurs, stop all testing and
isolate and remove any temporarily installed test spikes or test leads.
This tester has been designed with your safety in mind. However, no design
can completely protect against incorrect use. Electrical circuits can be
dangerous and / or lethal when lack of caution and / or poor safety
practices are used.
CAUTION

2
Before using the tester check the condition of the test leads and the fuses,
if using fused test leads.
The test leads must be free of cracks or any damages and must be insulated
as when they were new.
Always disconnect the test leads when changing the batteries by removing the
cover which give access to the batteries.
Always double check the lead connections before making any measurements.
For increased safety, use fused test leads (optional).
Don’t touch exposed wiring, connections or other “Live” parts of an electrical
circuit. If in doubt, check the circuit first for voltage before touching it.
Do not use cracked of broken test leads.

6.9 Auto-Low Resistance Detect.
While in insulation test mode, if the L. C. D. Module shows “LOW MW”,
stops the test immediately. This could mean that the insulation has a
breakdown, thus, you are now trying to inject very high voltage on a short
circuit. Trying to inject high voltage on a short circuit could reset the
instrument (specially if flashing occurs).
6.10 Timer.
The duration of the test is shown on the top right of the L. C. D. This is
particularly useful to verify that insulation does not break down within a
certain time or to make comparison. See Special Features (Pg.No.13)
for more Timer Functions.
6.11 Stop test.
To stop the test in progress, press the TEST button (3). The test will
immediately stop, discharge and the instrument will re-enable the Ener-
TM
Save mode automatically.
6.2 Auto-Stop.
Should the operator leaves the Instrument in the test mode with the
TM
Ener-Save disabled, the instrument will automatically stop the test
after a duration of 99.9 Seconds. (Auto-off still applies).
6.13 Auto Live / Voltage Warning.
Should the leads be placed onto a live system before starting the test, a
warning beeper will be automatically activated and your instrument will
display “Live Warning ... Circuit Live .. “ message. Let the instrument
discharge the circuit (in the case of capacitive system) or make sure that
the circuit under testing is not live.
6.14 Auto-Discharge.
At auto-stop or test completion, the instrument automatically discharges
the system under insulation test so that the dangerous high voltage is
discharged. The auto-discharge can be observed on the L. C. D.’s bar
graph so that the operator only removes the leads when the discharge is
complete. During discharge, a beep occurs so that the user does wait for
the complete discharge of the system under test. This is indicated

7. SPECIAL FEATURES
7.1 DAR = Dielectric Absorption Ratio.
The dielectric Absorption Ratio is the ratio of the Insulation Resistance
measured at 1 Min divided per the Insulation Resistance measured at 30
Seconds.
30 Seconds after starting a test (with EnerSave disabled), the tester will
beep, indicating the operator that the resistance value measured at 30
second now has been saved internally.
1 Minute after starting a test (with EnerSave disabled), the tester will beep
again, indicating the user that the DAR result is now computed, and
change the display formate to now display the DAR result.
7.2 PI = Polarization Index.
The Polarization Index or PI is the ratio of the Insulation Resistance
measured at 10 Minutes divided per the Insulation Resistance measured
at 1 Minute.
10 Minute after starting a test (with EnerSave disabled), the tester will
beep again, indicating the user that the PI result is now computed, and
change the display format to now display the PI result.
The tester willAuto-Stop at 10 minutes.
7.3 Digital Display.
The digital Liquid Crystal Display is large size.
It measures (W) 98mm X (H)24mm and has a 2 Lines of 16 Characters.
7.4 Automatic Battery Test.
When the tester starts, it test it’s batteries by drawing a heavy current from
the batteries. During that heavy current, it measures the battery voltage
and displays it for a few seconds on the display. During normal use, the
tester monitors the battery voltage, but without drawing a battery test
current. It just measures the battery while in normal use.
