6. Basic Electrical Operations
Refer to Figure A4 and the table below:
Item Description
Measure current on CH1, Range ± 55 mA (24 V loop
1
on CH2).
Measure current with external loop power (Range:
2
± 55 mA).
3 Measure DC Volts or DC mV on CH1.
4 Measure DC Volts (10 V) or DC mV (10 V) on CH1.
5 Switch test.
7. Pressure Operations
WARNING
Pressurized gases and fluids
are dangerous. Before connecting or
disconnecting pressure equipment, safely
release all the pressure.
CAUTION
To prevent damage to the
pressure station, do not let dirt get into the
pressure mechanism. Before connecting
equipment, make sure it is clean or use the
applicable dirt trap.
7.1 Release the Pressure/Attach the Device
Under Test
1. Open the pressure release valve (one turn) (Ref:
Figure A5).
2. Use the applicable adaptor to attach the device, (Ref:
Figure A7).
7.2 Vacuum Operation
Refer to Figure A6 and the procedure below:
1. Set to vacuum operation (–) (Ref: Item 1).
2. Turn the volume adjuster to mid-range or fully
clockwise (Ref: Item 2).
3. Seal the system (Ref: Item 3).
4. Set the approximate vacuum with the pump (Ref:
Item 4).
5. Adjust the vacuum with the volume adjuster (Ref:
Item 5).
6. On completion of test, open the pressure release valve
one turn (Ref: Figure A5) to release vacuum before
disconnection of device under test.
7.3 Pressure Operation
Refer to Figure A6 and the procedure below:
1. Set to pressure operation (+) (Ref: Item 1).
2. Turn the volume adjuster to mid-range (Ref: Item 2).
3. Seal the system (Ref: Item 3).
4. Set the approximate pressure with the pump (Ref:
Item 4).
5. Adjust the pressure with the volume adjuster (Ref:
Item 5).
6. On completion of test, open the pressure release valve
one turn (Ref: Figure A5) to release pressure before
disconnection of device under test.
