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. 

i

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 infor-
mation 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.
