7.7. Temperature measurement (optional)
A thermocouple adapter (0590 0002) is optionally available for measuring
temperature. Before using the thermocouple adapter, please carefully read
through the relevant section relating to the thermocouple adapter in the
documentation. Familiarize yourself with the product before using it. Pay
particular attention to the safety instructions and warning advice in order to
prevent injuries and damage to the product.
In this section, it is assumed that you are familiar with the contents of the
documentation relating to the thermocouple adapter.
Taking temperature measurements
✓ A thermocouple is attached to the thermocouple adapter.
✓ Instrument is switched on.
1. Connect the thermocouple adapter to the instrument: Insert the adapter
into the COM jack and into the V/Ω/diode/capacitance. jack. Ensure
correct polarity!
- The thermocouple adapter switches on automatically.
- The instrument is in AUTO V mode.
2. Activate AUTO RCDC measuring mode for temperature
measurements: press [] >2 s.
