5. Operation

This chapter describes the steps that have to be executed frequently when using the product.

5.1 Connect the probe

Plug-in probes

Plug-in probes must be connected before the measuring instrument is switched on so that they are recognised by the instrument.

Insert the connector of the probe into the probe socket.

Radio probes

Radio probes may only be used in countries in which they have been Type Approved (see application information of the radio probe).

A radio module (accessory part) is required for the use of radio probes. The radio module must be connected before the measuring instrument is switched on so that it is recognised by the instrument.

Each radio probe has a probe ID (identification number). This must be set in configuration mode.

See the chapter PERFORMING SETTINGS.

Possible reasons why probes are not found:

• The radio probe is not switched on or the battery of the radio probe is spent.
• The radio probe is outside the range of the measuring instrument.
• Sources of interference are influencing the radio transmission (e.g. reinforced concrete, metal objects, walls or other barriers between transmitter and receiver, other transmitters of the same frequency, strong electromagnetic fields).

If necessary, rectify the possible causes for the disruption to the radio transmission and start automatic probe detection again with

If further wireless probes are within reception range, the probe ID of a different wireless probe may be displayed.

If necessary: switch off other wireless probes or remove from the reception range, and start automatic probe detection again with
