Insulation resistance measurement with interference voltage detection

Insulation resistance measurement with test voltages of 50 to 1000 V. If interference voltage of greater than 15 V AC or 25 V DC is detected during insulation measurement, the device issues an optical and acoustic warning whereupon measurements cannot be launched. Afterward, automatic switching to TRMSAC+DC voltage measurement at 1 MΩ takes place and the currently measured voltage is displayed as Uext.

Polarization index (PI)

When test voltage is applied, insulation resistance is measured after one minute and after ten minutes. The polarization index is the ratio that results from the two measured values. In the case of electric drive units, a value of at least two indicates intact insulation and a value of greater than 4 indicates very good insulation.

Absorption index (DAR)

Practically speaking, the absorption index test is a quick polarization index measurement. The ISO values measured after 30 and 60 seconds are used to generate a ratio.

Kelvin connection for 4-Wire measurement (4-L) (milliohm measurement)

The 4-wire measurement compensates for influences resulting from cable and contact resistances which must not be neglected when measuring very small resistances. Measuring current can be set to 200 mA or 1 A. In this way, even extremely small contact resistances can be measured, for example at welded and riveted joints and on aircraft outer skins (lightning protection and wick test), or equipotential bonding is measured in accordance with UN ECE R100 in hybrid and electric vehicles.

2-Wire Rlo measurement with 200 mA test current per EN 61557

Low-resistance measurement per EN 61557-4 for earth, protective and equipotential bonding conductors. If excessive interference current is detected during insulation measurement, the device issues an optical and acoustic warning whereupon measurements cannot be launched.

RMS value with distorted waveforms

The utilized measuring method allows for waveform-independent TRMS measurement of alternating quantities (AC) and pulsating quantities (AC and DC) for voltage and current at up to 100 kHz.

Activatable filter for V AC measurement

A 1 kHz low-pass filter can be activated if required, for example when measuring cables with parasitic external signals. The input signal is checked by a voltage comparator for dangerous voltages as long as the low-pass filter is activated, and these are indicated at the display if applicable.

Diode testing with constant current Ik = 1 mA

Testing of the polarity of diodes and checking for short-circuits and interruptions in electrical circuits. The test voltage source makes it possible to measure LEDs and reference diodes up to 4.5 V, e.g. also white LEDs.

Fast Acoustic Continuity Test Ik = 1 mA

Testing for short-circuiting or interruption in the sound switch position. The threshold value for acoustic signaling can be set to 1, 10, 20, 30, 40 or 90 Ω.

Automatic/manual measuring range selection

Measured quantities are selected with the rotary switch. The measuring range can be automatically matched to the measured value or selected manually for quick, repetitive measurements.

Color graphic display

A high-resolution transmissive 3½" TFT color graphic display with 320 x 480 dots is used for measured values and menu navigation. The display is easily readable from all directions, as well as under difficult lighting conditions (controllable with light sensor). Graphic representation permits user-friendly menu navigation including help texts.

Analog bar graph for quick trend displays

The bar graph (with additional negative axis range for zero-frequency quantities) permits faster detection of measured value changes as compared with digital value displays.

Automatic storage of measured values

The data hold function automates the storage of measured values after they have settled in. A patented process assures that random values are not saved to memory in the case of rapidly changing measured quantities, but rather the actual measured value. The stored measured value is displayed as a digital value. The bar graph continuously indicates the momentary measured value.

Overload protection

Overload protection safeguards the instrument in all measuring functions for up to 1000 V. Voltages of greater than 1000 V and currents of greater than 1 A are indicated acoustically. Fuse appears at the display if the fuse for the current or mΩ measurement input blows.

Battery charge level – power saving circuit

The battery charge level is accurately indicated in the graphic display. This device is switched off automatically if the measured value remains unchanged for a period of between 10 and 59 minutes (adjustable) if none of the controls are activated during this time and continuous operation is not activated.

Automatic blocking sockets (ABS)

All current ranges are implemented via a single connector jack which prevents any possibility of operator error. The automatic blocking sockets prevent incorrect connection of the measurement cables, as well as a selection of the wrong measured quantity. Danger to the user, the instrument, and the device under test resulting from operator error is thus ruled out. Patented (patent number EP 1801 598 and US 7,439,725)

Housing and protective cover for harsh conditions

• New housing design
• Separate fuse compartment
• Quick-change rechargeable battery

This instrument is protected against damage in the event of impacts or dropping by means of a soft rubber cover with a tilt stand. The rubber material also assures that the instrument doesn't move if it's set up on a vibrating surface.

Data interfaces

This instrument can be remote and momentary and saved measurement data can be read out via Bluetooth. For PC, the complete software IZYTRONIQ or METRAHIT IM Data Reader is required to this end.

DAkkS calibration certificate

This multimeter is furnished with a DAkkS calibration certificate, which is also recognized internationally (EA, ILAC). After the user-specified calibration interval has elapsed (recommended interval: 1 to 3 years), the multimeter can be inexpensively recalibrated in our proprietary DAkkS calibration laboratory.
