Calibration Procedure (CH1): Resistance (measure) (True
Ohms)
Note:
‘True ohms’ measurement is more accurate than
‘Standard’.
The calibration procedure is the same as that for Resistance
(measure) (standard) (ref.
Section 10.9
) except:
In the calibration menu (Ref:
Section 10.2
) select ‘True
Ohms’ instead of ‘Standard’.
To check the calibration is correct, refer to Table 10-12
.
