FEATURES INCLUDE:
 Test voltages (New)
- 50 V, 100 V, 250 V, 500 V and 1000 V.
 Variable test voltage (New)
- Adjustable test voltage from 10 V to 1000 V.
 2% test voltage accuracy
- The output test voltage is maintained within the tolerance or
-0% +2%
 PASS/FAIL indication (New)
– PASS or FAIL displayed depending on threshold voltage
 Stabilised test voltage
- The voltage is feedback controlled to ensure it remains within
specification throughout the full test range
 Test voltage display (New)
- The actual test voltage is displayed on the smaller digital
readout, with the measurement on the larger digital display.
 Measurement range displayed (New)
- The test range is displayed during selection
 Measurement voltage display
- The measurement voltage is displayed during the test
 Analogue arc
- The display also features an analogue arc to replicate the
response of a moving coil display.
 PI and DAR
- Polarisation Index (PI) and Dielectric Absorption Ratio (DAR)
functions
- Polarisation Index (PI): 10 min / 1 minute ratio
- Dielectric Absorption Ratio (DAR ): 60 sec / 30 sec ratio
 Timed testing
- Automatically test to a time limit
 High test range
- Insulation testing up to 200 GΩs at 1000 V.
 Silicon leads
- High quality flexible silicon test leads are comfortable to use and
prevent measurement errors on GΩ ranges above 5 GΩ.
 Test inhibit
- prevents testing if voltages in excess of 30, 50 or 60 V (set by
the user) are detected when making insulation tests. Default is
50 V.
 Insulation buzzer
- The buzzer can be set to buzz if the insulation resistance is
above a user adjustable limit, set in the Setup menu.
 Test Lock
- Holds insulation test on continuously.
 ESD display option (New)
- Swap display from kΩ, MΩ, GΩ to 10^5, 10^6, 10^7 etc
* Dependent on model
Test ranges extend from 2 GΩ to 200 GΩ depending on test voltage
as below:
 50 Volts. 10 GΩ
 100 Volts. 20 GΩ
 250 Volts. 50 GΩ
 500 Volts. 100 GΩ
 1000 Volts 200 GΩ
 Variable 50 V to 1000 V dependent on test voltage
CONTINUITY (RESISTANCE) TESTING:
 Single resistance range (New)
- One range fully automatic from 0.01 Ω to 1.0 MΩ.
 Bi-directional testing (New)
- Option for automatic bi-directional testing without
reconnecting leads.
 200 mA or 20 mA
- Either 200 mA or 20 mA continuity test currents are available.
20 mA test current will considerably increase battery life.
 Lead null
- Lead resistance compensation (NULL) operates up to 10 Ωs 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 Ω to 100 Ω in 5 steps.
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
 Analogue arc measurement to 1000 V ac/dc
 Automatic display of frequency during voltage measurement.
DISPLAY:
The display offers a combination of Analogue arc and a dual digital
readout:
Analogue arc:
 Full display width analogue arc.
 Analogue arc display shows essential charge and discharge
characteristics not visible on a digital display.
 Single pointer “needle” response is similar to a moving coil
meter.
Setup functions allow control of Buzzer limit alarms, Continuity test
currents, KΩ/MΩ/GΩ or 104 /105 /106 (New)
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.
 Supply frequency (when measuring volts).
 Test mode eg. PI, DAR or t ( t = Timer mode).
