Calibrating
The N1913/1914A EPM Series power meters are able to perform
calibration for the U8480 USB thermocouple sensor via the front panel
and SCPI. The N1913/1914A EPM Series power meters also support auto
calibration (Auto Cal) for the U8480 USB thermocouple sensor. Both
internal (Int) and external (Ext) calibration is supported by the
N1913/1914A EPM Series power meters.
Figure 8-6 Calibration type
The Auto Cal state is determined by the state of the calibration type as
shown in Figure 8- 6. If the calibration type is set to Int, you will be able
to toggle between On and Off under the Auto Cal state. If the calibration
type is set to Ext, the Auto Cal state will be set to Off and the softkey will
be greyed out.
When calibration is performed via the front panel or SCPI, the following
message will appear:
