Do not touch the conductive ends of the test probes when the instrument has been activated for the measurement of insulation resistance.
➭ Connect the measurement cables to the accessible M and sockets, using the included probe for connection to the M socket if possible. RISO ➭ Set the rotary switch to “RISO” or “COIL”. ➭ Interference voltage testing (V AC+DC TRMS) is conducted in this switch position. ! Attention! If interference voltage of roughly Uext < 15 V AC or < 25 V DC is detected, visual and acoustic warnings are generated. Measurement is disabled as well.
8.2.2 Performing Insulation Measurement ➭ Don’t read the measurement results until the display has settled in. The high-voltage symbol next to the battery level display blinks during measurement. Auto-ranging is active during insulation resistance measurement. A DATA function which is matched specifically to the insulation measurement can be activated for automatic retention of valid measured values (see section 7.2.1).
Selecting the Type of Measurement 8.3.1.1 Preparing for Measurement MENU RISO Connect COIL TEST ADAPTER and measurement cables COIL U ! 0 V! Pulse Current up to 600 A is Possible! S– A M COIL USurge max 1200 V! W Example with Star Connection m/4 OK Coil / 1-Ph. Motor / 3-Ph. Motor ESC 3 x > Measurement View OK 1-Ph. Motor: AC motor (L1) 3-Ph. Motor: 3-Phase motor (U-V, U-W, V-W) Coil Motor with up to 15 coils (L1 - L15) ➭ Select polarity: unipolar or bipolar (see below).
Test Voltage (Uset = 1000 V) Test voltage for the inter-turn short circuit measurement is permanently set to 1000 V and cannot be changed. ➭ You can delete each measurement in order to repeat it by selecting the desired table row for U-V, U-W or V-W with the or scroll key and pressing the Delete softkey. Connection and Contacting ➭ Make sure that the device under test is voltage-free. Note Interference voltage cannot be detected in combination with the COIL TEST ADAPTER (COIL ADAPTER 50 mH).
In the case of permanent-field motors, inter-turn short circuit measurement is dependent on rotor position. This also applies to squirrel cage motors with large inductances which result in more frequently occurring remanence. In this case, the bipolar setting must be selected for the inter-turn short circuit measurement. First of all, measurement must be performed at each coil with positive polarity. Afterwards, each coil is measured once again with reversed polarity.
8.3.2 Inter-Turn Short Circuit Measurement with the ADAPTER XTRA* In combination with the optional COIL ADAPTER XTRA, inter-turn short circuit measurements with a test voltage of 1000 V are possible within an inductance range of 10 μH to 5 H (100 Hz). Switch set to High: 5 mH to 5 H Low: 10 μH to 50 mH This range corresponds to motors in accordance with DIN standards with power ratings of roughly 0.16 kVA to 80 MVA. Switch set to High: from roughly 0.

RISO COIL ➭ Repeatedly press the Func softkey until the measurement view for DAR appears at the display.
Polarization index testing is recommended for electric machines. This procedure involves expanded testing of insulation resistance RISO. DC measuring voltage from the multimeter is applied to the insulation for a duration of 10 minutes. The measured RISO value is documented after one minute, and after ten minutes. If the insulation is good, the value measured after ten minutes is higher than the value measured after one minute. The relationship between the two measured values is the polarization index.
8.6 ! Voltage Measurement Warning! Be aware of the fact that dangerous voltage spikes are not displayed during measurement with the low-pass filter. Measure voltage without the low-pass filter first, in order to be able to detect any dangerous voltages. Note Rotary selector switch position “RISO” is available for the detection of interference voltage during insulation resistance measurement. Use switch position V , V or V in order to perform precise voltage measurements.
Voltage Comparator for Displaying Dangerous Voltage Voltage Comparator for Displaying Dangerous Voltage The input signal or measuring signal is checked by a voltage comparator for dangerous spikes, because these do not appear at the display when the low-pass filter is used.
