Frequently Asked Questions - RU1085 IFM

How do I turn on the IFM RU1085 multimeter?

To turn on the multimeter, press the 'ON\/OFF' button located on the front of the device.

What should I do if the multimeter does not turn on?

Check if the batteries are properly installed and not depleted. Replace the batteries if necessary.

How do I change the measurement unit on the multimeter?

Use the unit selection button to switch between measurements (voltage, current, resistance).

Why does the multimeter display 'OL'?

'OL' means 'Over Limit' or that the measured value exceeds the maximum range of the multimeter. Check the selected measurement range.

How do I calibrate the IFM RU1085 multimeter?

Refer to the user manual for calibration instructions. This may require a reference standard.

The multimeter gives inconsistent results, what should I do?

Ensure the probes are in good condition and properly connected. Also check the connection to the circuit being measured.

How do I test continuity with the multimeter?

Select the continuity test mode and touch the two probes together. A beep will confirm continuity.

Can I use the IFM RU1085 multimeter to measure AC and DC voltages?

Yes, the IFM RU1085 multimeter can measure both AC and DC voltages. Select the appropriate mode before measuring.

How do I interpret the results displayed by the multimeter?

Read the value displayed on the screen, which indicates the measurement according to the selected unit.

What should I do if the multimeter screen is cracked?

If the screen is cracked, it is recommended to contact customer service for repair or replacement.

USER MANUAL RU1085 IFM

The encoder transforms rotational movement into pulse sequences. These allow the measurement of linear distances and angular move- ment as well as the determination of positions. Electrical connection Disconnect power from the installation before connecting or dis- connecting cables or connectors! Unused wires must be insulated to avoid short circuits and cross faults. Short-circuit protection 5 V TTL version: outputs short-circuit protected against 0 V 10...30 V HTL version: outputs short-circuit protected against 0 V and L+ for maximum 1 minute Standard wiring:

If there is a deviation, the encoder must be connected as indicated on the label on the housing cap. The wires L+ (sensor) and 0V (sensor) are internally connected to the supply voltage. When using external electronics which regulate the supply voltage these wires can be used as test wires. If unused, these wires must be connected to the supply voltage or insulated. Depending on the version, the electrical connection is made via the cable or via cables to be obtained separately. When using suitable cables the maximum cable length is 100 m for the 5 V TTL version and 300 m for the 10...30 V HTL version.

The braided screen in the cable is connected to the encoder housing. Output signals The encoder provides digital pulse sequences at the output stages. The outputs A and B are electrically offset by 90°. Thus the direction of rotation can be evaluated in the external electronics. The combined zero index is provided once in a mechanical revolution of the shaft. In case of power failure it can be used as a reference point within a revolution. The inverted output signals are used for external electronics with dif- ferential voltage input to filter interference. Installation Do not hit the shaft, do not use a file or similar tool on the shaft: This could destroy the unit! The encoder can be screwed to the angle bracket. The shaft should be connected using a flexible bellows or spring disc coupling to compen- sate for shaft displacement and to protect the encoder against dam- age. Linear movements can be transformed into a rotational movement using a measuring wheel or rack and pinion. For mounting the maxi- mum permissible shaft loads of the encoder must be taken into account.
