a temperature probe is used, ATC and the sample temperature are displayed. If the meter does
not detect a temperature probe, it automatically switches to the manual temperature
compensation mode and MTC appears. MTC temperature should be set. (See 4.2, 4.3)
Note:
The meter accepts
NTC 30 kΩ temperature sensor.
3.4 Using the memory
