98x Teraohmmeter/IR Tester

98x Teraohmmeter/Insulation Resistance (IR) Tester

The 98x Series Teraohmmeter meets today’s demanding requirements for higher voltage IR (insulation resistance) testing.

In a never ending race for higher efficiency, electric vehicles and solar panel arrays are now operating with voltage rails up to 2.5 KV.  This is no place for a 1 KV tester, it’ time to step up to a Vitrek 98x!

Built upon the same DSP technology that has established Vitrek as a leader in hipot test systems, the 98xi devices feature a unique combination of performance features including:

Multi-dwell Functionality (multiple steps without having to return to zero between steps)

High-speed Testing (with dwell times as low as 100 ms)

Pico-Amp Leakage Measurement (with stable and precise 50 Teraohm IR readings)

Continuously Variable IR Test Voltage (adjustable over the full output range of the instrument)

Multi-mode Insulation Resistance Tests (three test modes – end on time, end on pass, end on fail)

Capacitance Test Modes (critical for solar panels, cable harnesses and other capacitive loads)

For applications requiring insulation resistance tests of multiple conductors, the Vitrek 98×1 IR Testers have the capability of directly controlling up to

four 64-channel Vitrek 964i high-voltage scanners. Utilizing a PC equipped with Vitrek’s QT Enterprise™ software, the same instrument can handle up to 1020 test points.

Expanding the possibilities of High Voltage Resistance Measurement

The new 981i and 983i Teraohmmeters are designed to tackle the toughest High Resistance measurement applications. Demanding applications that most other IR testers won’t measure up to. So when it’s time to test higher voltage IR values like today’s electric vehicle systems and higher voltage solar arrays — look to Vitrek to deliver the IR tester you need for your production line.

What sets the Vitrek 98x Series IR testers apart from the others?
For starters, these units are based on Vitrek’s proven DSP technology — so they have the ability to work into capacitive loads where most others do not. And when it comes to output voltage range, Vitrek delivers — with up to 6.5 KVDC for the 981i and up to 11KV with the 983i.

Need to Perform an Insulation Resistance Test on a Multi-Conductor Cable Harness?
The 981i and 983i have the ability to directly control up to four 64 channel HV scanners, right out of the box. That is up to 256 test points and using a PC with Vitrek’s Q-Test software you can expand the count up to 1020 test points. The HV Switching System of choice is the Vitrek 964i, which can hold eight 8-channel switching cards — available in 7, 10 and 15KV ratings.

In a never ending race for higher efficiency, electric vehicles and solar panel arrays are now operating at 2.5KV.
This is no place for a 1KV tester, it’s time to step up to a 98x!

Product Features and Benefits

Highest Range of IR Test Voltage — Choose from 6.5KVDC or 11KVDC maximum output

Fast IR Readings — High speed output control with Dual Coldfire microprocessors and Dual DSPs to provide dwell times as low as 100ms

High Resistance Measurement Range — Transfer measurement up to 150 Teraohms

Expansive Test Sequency Memory holds up to 100 tests with up to 254 steps per insulation resistance test. Tests can be selected via front panel, Ethernet, RS232 or with optional GPIB

Multi-Dwell Functionality — permits dwells at different voltage levels without having to return to zero between test steps – dramatically simplifying advanced analysis of dielectric properties

Ethernet, RS232, Digital I/O & Scanner Control — All standard interfaces – Provides the highest level of test automation. GPIB available

Pico-Amp Leakage Measurement ensures that even the lowest leakage current levels are accurately detected and 150 Teraohm transfer and 50 Teraohm IR readings are stable and precise

Test Specific Fixture & Cable Compensation — Automatically calibrate out offset errors caused by test fixture insulation resistance and capacitive and leakage

Multi-Mode IR — Values up to one Teraohm or more can be obtained with precision in your choice of 4 IR test modes – end on time, end on pass or end on fail or steady or rising

Continuously Variable Insulation Resistance Test Voltage — Unlike many IR testers which limit you to 3 or 4 discrete test voltages, the 981i allows you to select the test voltage you need from 30V to 6.5KV with 1 volt resolution. The 983i provides outputs from 60V to 11KV

Capacitive Loads — The 981i & 983i are specified for use with capacitive loads, most IR testers are not. This means the 981i & 983i are exceptional at performing IR tests on cabling PV panels and CMC devices

Measure IR on Grounded Loads — Some DUTs cannot be isolated from earth ground, add option HSS2 to make precise IR measurements on grounded loads

Light Weight Design — Better reliability, easier on your back. Compare the 4.5 kg 981i/983i to whatever you’ve been using. Vitrek delivers superior performance in a smaller, lighter footprint

3 Year Extended Warranty — 1 year standard, total of 3 years extended warranty with registration and annual factory calibration. Built-in reliability you can count on for years to come

Safety Tested per EN 61010-1. EMC compliant to EN 61326-1

Manual Test Mode — Allows for variable voltage output during testing with continuous measurements and pass/fail indiciation until the user stops the test

Made in the U.S.A.
