CHAPTER 1
GENERAL ASPECTS
1.1 Features of the meter
⚫ Selectable Test Voltage up to 5000 V (ISO 5 model) o 10.000V (ISO 10
model): Test voltages can be set to any desired value from 100V to 5000V ISO 5
Model o 100V to 10.000V ISO 10 model with steps of 10V up to 1000V and steps of 25V
above 1000V.
⚫ High Insulation resistance measurement: Insulation resistance measurement from
50kΩ to 10TΩ (ISO 5) o 20TΩ (ISO 10) .
⚫ Noise rejection - 8mA: High Noise immunity allows accurate measurement under noisy
environment.
⚫ Polarization Index: Polarization index (PI) testing is an extension of the insulation
resistance test and is designed to check specific issues such as moisture and insulation
deterioration.
⚫ Dielectric Absorption Ratio: DAR measurement is a diagnostic test similar to the
Polarization Index (PI), but DAR takes the ratio of the Insulation Resistance usually
measured at 30 sec and 1 min.
⚫ Dielectric Discharge Test: Dielectric Discharge(DD) test is a diagnostic insulation test
that allows aging and deterioration to be assessed.
⚫ Step Voltage Test: Step Voltage Test is designed as a controlled over-voltage or proof
test to provide an additional evaluation of the insulation system integrity.
⚫ Ramp Diagnostic Test: The Ramp Test is performed with a slowly rising voltage.
⚫ Software Selectable Filter: User selectable software filter can be used depending on
noise levels. This help in accurate reading in noisy environments.
⚫ Capacitance Measurement: Capacitance can be measured from 1nf to 50uF.

6
⚫ Go- NoGo Function: User can set an insulation resistance limit below which user will be
alarmed about the quality of insulation.
⚫ Insulation Graph Display: Insulation Resistance trend can be displayed over the time in
graphical form.
⚫ Communication Interface: Bluetooth 2.0 & 4.0 Class II and electrically isolated USB 2.0
communication.
⚫ Software and Mobile Application: It has data logging and monitoring software for
window system and an interactive mobile application for android.
⚫ File Explorer: It has file explorer to view the datalog file on TFT display.
⚫ Audio Read-Out: Audible test result on completion of test for awkward locations.
⚫ Rechargeable Battery: Li-Ion 3 Cell Battery with charging current of 1A.
⚫ Internal Data logging: It has internal data logging feature. It can log up to 2000 test
files with customer information and time stamp.
⚫ Selectable test time: User can set the test time to any desired test time from 45 sec to
99 min 59 sec.

CHAPTER 2
USER AND BATTERY SAFETY
USER SAFETY:
Following safety measures should be taken while using the instrument:
 The circuit under test should be turned off /denergized(dead), all its terminals should be
isolated, the circuit should also be discharged and checked before the insulation is tested.
 During the test please make sure that you do not touch any of the test leads. The caution
symbol on the measurement screen indicates that hazardous voltage is present at the
test leads.
 After test completion you should make sure that the load is completely discharged
because this charge can be dangerous.
 The voltage indicator and internal discharge should be treated like additional safety
devices and not a substitute for the general practices.
 Insulation testing in wet conditions can be hazardous. It is recommended that the
instrument should not be used under these circumstances.
 During control from bluetooth or USB the test can be started at any time. Please make
sure the connections are proper before turning on the test.
 Please use only the leads supplied with the meter for testing the device.
NOTE: INSTRUMENT SHOULD BE OPERATED BY SUITABLY TRAINED AND
COMPETENT PERSONS ONLY
BATTERY SAFETY:
Following safety measures should be followed while handling the battery:
 Do not disassemble or change the battery. This battery consists of safety and protection
devices which if damaged can cause harm to the battery.
 Do not heat the battery in any way.
 Do not pierce the battery.
 Do not expose the battery to water.
 Do not subject the battery to shocks.

8
 Never short circuit the battery pack.
 In case the battery starts leaking, do not allow the liquid to come in contact with skin or
eyes. If by mistake you make contact, wash the affected area with water and contact
doctor.
 Keep the battery away from children.
 Do not expose the battery to extreme temperatures. Extreme temperature will reduce
the lifetime of the lithium ion battery.
