Checking Voltage Available
WARNING
Personal injury or property damage caused by fire or explosion may occur it this test is attempted in any area which
contains a potentially explosive atmosphere or has been classified as hazardous.
To check the Voltage Available at the instrument, perform the following:
1. Disconnect the field wiring from the control system and connect equipment as shown in figure 4‐3 to the control
system terminals.”
2. Set the control system to provide maximum output current.
3. Set the resistance of the 1 kilOhm potentiometer shown in figure 4‐3 to zero.
4. Record the current shown on the milliammeter.
5. Adjust the resistance of the 1 kilOhm potentiometer until the voltage read on the voltmeter is 9.0 Volts.
6. Record the current shown on the milliammeter.
7. If the current recorded in step 6 is the same as that recorded in step 4 (± 0.08 mA), the voltage available is
adequate.
