CHAPTER 1GENERAL ASPECTS1.1 Features of the meterSelectable Test Voltage up to 5000 V: Test voltages can be set to any desired valuefrom 100V to 5000V with steps of 10V upto 1000V and steps of 25V above 1000V.High Insulation resistance measurement: Insulation resistance measurement from50kΩ to 10TΩ .Noise rejection - 8mA: High Noise immunity allows accurate measurement under noisyenvironment.Polarization Index: Polarization index (PI) testing is an extension of the insulationresistance test and is designed to check speciﬁc issues such as moisture and insulationdeterioration.Dielectric Absorption Ratio: DAR measurement is a diagnostic test similar to thePolarization Index (PI), but DAR takes the ratio of the Insulation Resistance usuallymeasured at 30 sec and 1 min.Dielectric Discharge Test: Dielectric Discharge(DD) test is a diagnostic insulation testthat allows aging and deterioration to be assessed.Step Voltage Test: Step Voltage Test is designed as a controlled over-voltage or prooftest 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 onnoise levels. This help in accurate reading in noisy environments.Capacitance Measurement: Capacitance can be measured from 1nf to 50uF.3

Go- NoGo Function: User can set an insulation resistance limit below which user will bealarmed about the quality of insulation.Insulation Graph Display: Insulation Resistance trend can be displayed over the time ingraphical form.Communication Interface: Bluetooth 2.0 & 4.0 Class II and electrically isolated USB 2.0communication.Software and Mobile Application: It has data logging and monitoring software forwindow 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 testﬁles with customer information and time stamp.Selectable test time: User can set the test time to any desired test time from 45 sec to99 min 59 sec.The home screen of the meter is as shown below:4

5USER 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 beisolated, 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 cautionsymbol on the measurement screen indicates that hazardous voltage is present at thetest leads.After test completion you should make sure that the load is completely dischargedbecause this charge can be dangerous.The voltage indicator and internal discharge should be treated like additional safetydevices and not a substitute for the general practices.Insulation testing in wet conditions can be hazardous. It is recommended that theinstrument should not be used under these circumstances.During control from bluetooth or USB the test can be started at any time. Please makesure the connections are proper before turning on the test.Please use only the leads supplied with the meter for testing the device.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 protectiondevices 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.CHAPTER 2USER AND BATTERY SAFETY

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

CHAPTER 4CONNECTION OF TEST LEADS TO METERThe meter has 3 probes guard, positive and negative. Each probe consists of 2 ends. One of these ends is the probe handle which has to be connected to the meter and the other end will depend upon the type of accessories ordered. Figure below shows the probe handle for the single probes(Guard and positive) and double probe which is connected to the negative terminal. Both the handles have a rotor for locking the probe to the meterDue to the locking mechanism of the probes the probes remain ﬁrmly connected to the meter during the test. Following are the steps to connect the probe to the meter:Insert the probes into the meter as shown in the below diagram:Single probe handleDouble probe handleProbe rotorNegativeGuardPositive9
