5.Operation
This chapter describes the steps that are executed frequently when using the product.
5.1 Connecting a 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.
iInsert the connector of the probe into the probe socket of the measuring instrument.
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 measuring instrument.
Each radio probe has a probe ID (identification number) which must be set in configuration mode.
º See chapter PROBE, p. 47.
5.2 Switching on/off
²Switching the instrument on: i Press 
.
-Measurement view is opened: The current reading is displayed, or
---- lights up if no reading is available.
Instruments with a memory: The activated location is displayed (topmost line).
-or-
The instrument is switched on for the first time, a reset was carried out or the power supply was interrupted for a lengthy period of time:
-The Language function is opened. º See the chapter LANGUAGE, p. 50.
