Features

Insulation testing up to 2.5 kV and 200 GO range in a hand held instrument
Guard terminal for high resistance accuracy
Adjustable insulation test voltage from 50 to 2500 V
Stabilized insulation test voltage: The voltage is feedback-controlled to ensure it remains within specification throughout the full test range
Rechargeable options for mains and car charging
Single range, faster continuity testing from 0.01 O to 1 MO
Polarization Index (PI) and Dielectric Absorption Ratio (DAR)
CAT IV 600 V applications
2% test voltage accuracy: The output test voltage is maintained within the tolerance of -0%, 2%, and 2 V
Test voltage display: The actual test voltage is displayed on the smaller digital readout, with the measurement on the larger digital display
Measurement range displayed: The range voltage is displayed during selection
Measurement voltage display: The measurement voltage is displayed during the test
Analog arc: The display also features an analog arc to replicate the response of a moving coil display
Timed testing: Automatically test to a time limit
200 GO range: Insulation testing up to 200 GO at =1000 V
Insulation buzzer: The buzzer can be set to sound if the insulation resistance is above a user adjustable limit, configurable in the Setup menu
Test lock: Holds insulation test on continuously
Designed for the electrical and industrial markets
Test result storage and review and Bluetooth download
Live circuit detection and protection
IP54
Weatherproof: Every tester is sealed to IP54, providing a weatherproof case to reduce the chances of water ingress, including the battery and fuse compartment
Tough housing: Rubber over moulding combines the tough shock absorbing outer protection with excellent grip, on a strong modified ABS housing, providing an almost indestructible case
Storage and downloading results: Smooth Bluetooth and pairing procedures makes this tester easy to pair and download data and the test results are downloaded to a CSV file which can then be opened as an Excel spreadsheet

Test inhibit

Prevents testing if voltages in excess of 25, 30, 50, 75 or 100 V (set by the user) are detected when making insulation tests (default is 50 V)
15 nF capacitance inhibit where testing above 1000 V to prevent hazardous charge developing on the circuit under test

Test ranges extend from 10 GO to 200 GO depending on test voltage as below

50 V/10 GO
100 V/20 GO
250 V/50 GO
500 V/100 GO
1000 V/200 GO
2500 V/200 GO
For voltages of 1000 V and above, or expected insulation values over 100 MO the guard terminal should be considered to reduce measurement error

Continuity (resistance) testing

Single resistance range: One range fully automatic from 0.01 O to 1 MO
Auto test current selection: Automatically uses the preferred test current for the load resistance under test
Bi-directional testing: Option for automatic bi-directional testing without reconnecting leads
Fast response time: Response time on contact buzzer has been reduced
200 or 20 mA: Either 200 or 20 mA continuity test currents are available and 20 mA test current will considerably increase battery life
Lead null: Lead resistance compensation (NULL) operates up to 10 O of resistance
Buzzer: ON/OFF selected by simple push button
Buzzer limit: Continuity buzzer limit alarm provides adjustment of the maximum resistance the continuity buzzer sounds. This is adjustable from 1 to 200 O in 12 steps
Display PASS/FAIL (?/?) warnings: For use where buzzer indication may be disruptive

Insulation resistance testing

The feedback controlled insulation test voltage is now accurate to 2% -0% compared to the original 20%, providing a more accurate test voltage without the risk of over-voltage damage to circuits.
A variable range allows the exact test voltage to be selected from 50 to 999 V in 1 V steps, (1 to 2.5 kV in 10 V steps) providing 1100 test voltage options

Variable insulation voltage

The variable mode provides a unique solution for awkward insulation voltage measurement applications. The range option allows an insulation test voltage from 50 to 999 V in 1 V steps, or 1 to 2.5 kV in 10 V steps.

Guard terminal

The guard terminal (G) is a third terminal on the connection panel. Connection of the guard terminal on certain applications provides a return path for parallel leakage currents that could otherwise create significant errors in the insulation measurement. This is especially so for surface contamination of equipment or cables.

Voltage measurement

True RMS voltage measurement to 600 V AC or DC with resolution from 0.1 mV.

Digital voltage measurement up to 600 V AC/DC
Automatic display of frequency during voltage measurement

Display

The display offers a combination of analogue arc and a dual digital readout:

Analog arc:

Full display width analogue arc
Arc display shows essential charge and discharge characteristics not visible on a digital display
Single pointer "needle" response has a similar response to a moving coil meter

Dual digital display:

Large main digital readout for good visibility of all main measurement results
Second digital display for additional data such as: Insulation test voltage, insulation leakage current, and supply frequency (when measuring volts)

Setup functions

Continuity buzzer limit alarms
Insulation buzzer limit alarms
Insulation LOCK
Insulation test timer duration
Back-light ON duration
Sleep timer
Continuity test currents
Factory reset

Batteries

Battery requirements are 6 x AA batteries of either standard alkaline or nickel metal hydride (NiMH) rechargeable type, providing a minimum of 3000 insulation tests at 1000 V. This tester is enabled for internal charging when used with the optional charging pack (sold seperately).

Safety

Designed to be exceptionally safe to use, fast detecting circuitry prevents damage to the instruments if accidentally connected to live circuits or across phases. Specifically, all instruments:

Meet the international requirements of IEC61010 and EN61557
Live circuit detection inhibits insulation testing on circuits above 25, 30, 50 74 or 100 V default (50 V)
Live circuit detection and test inhibit on continuity measurements
Default display of live circuit voltage on all ranges
Detection and inhibit functions even if the protection fuse has failed
Suitable for use on CAT IV applications and supply voltages to 600 V
Automatic capacitance detection to prevent hazardous charge
