Example
FS = 350 mbar input current = 19.986 mA
Adjust instrument reading to:
19.986 x 350 mbar = 349.8 mbar
20 mA
4.3.2 Voltage Input (Figure 4-2)
Preparation
1. Set SW3-7 to open and SW3-8 to closed.
2. Connect the power source to pin 1 to +ve and pin 3 to -ve.
Procedure
1. Switch the instrument on.
2. Select control mode.
3. Set the power source to approximately 10 V and record the DVM reading.
4. Calculate the following:Instrument reading = DVM reading x FS
10V
5. If necessary, adjust potentiometer RV20 for this value.
6. Switch the instrument off.
Example
FS = 350 mbar applied voltage = 9.978 V
Adjust instrument reading to:
9.978 x 350 mbar = 349.2 mbar
10 V
Reassemble the instrument as detailed in the section 4.4.
