3. Operations
◆
Press to select a pressure unit (Section 3.1.4 and Table 3-2).
◆
Press to display the information of the pressure module.
3.1.9 Scaling
◆
When a current or voltage is being measured, the calibrator can scale the signal to display pressure or % of full scale.
◆
Press to set correlative parameter.
3.1.10 Zero
◆
When offset occurs a Pressure Zero or Electrical Zero can be applied to the High/Low Range pressure, Current/Voltage
measure, or external pressure module.
◆
Zero can be done within 1%FS of the pressure or 0.1%FS of the Current/Voltage.
3.1.11 Step
1.Setup
◆
Press to setup the step parameter in SOURCE mode.
◆
Starting point (Vs) and Ending point (Ve).
1) They cannot be equal (if Vs<Ve, ascend first and Vmin=Vs, Vmax=Ve. If Vs>Ve, descend first and Vmin=Ve, Vmax=Vs).
2) The unit is the same as the unit of Source item.
◆
Step Mode and size. The output values of the steps are calculated as follows:
1) The step size of point number(N), and the output values(n):
Vmin+ (n-1) * ( Vmax-Vmin ) / (N - 1), n = 1
