9.2.6. AC POWER CONFIGURATION
The E-Series digital electronic systems will operate with any of the specified power regimes. As long as
instrument is connected to 100-120 VAC or 220-240 VAC at either 50 or 60 Hz it will turn on and after about 30
seconds show a front panel display. Internally, the status LEDs located on the Relay PCA, Motherboard and
CPU should turn on as soon as the power is supplied.
On the other hand, some of the calibrator’s the dry air pump must be properly configured for the type of power
being supplied to the instrument. Figure 2-3 shows the location of the Pump AC Configuration jumper.
