3.5.3 One-point level
The One-point level test should be combined with one of the following output verification
tests:
Analog Output
Relays K1/K2
To run a One-Point Level Verification test do the following:
1. Ensure that the TankMaster WinSetup program is up and running and open the
Proof Test window.
2. Select the One-Point Level Verification check box (see “Maintenance” on
page 29).
3. Select one of the check boxes for Analog Output or Relays K1/K2 verification tests
depending on the output option that is used.
4. Click the Start Guided Proof Test button and follow the instructions in the Guided
Proof Test wizard.
5. Now the One-point level test will be performed followed by the selected output
verification test.
6. Compare the level presented in TankMaster with a second reference such as the
BPCS level sensor or a manual hand dip (see the Rosemount 5900S Radar Level
Gauge Reference Manual
for a description of how to perform hand dipping).
7. Once the One-point verification test is finished, TankMaster will automatically
proceed with the appropriate output verification test depending on the selected
option in the Proof Test window:
Relays K1/K2: verify energized and de-energized states for each relay K1and K2.
See “Relay output verification” on page 28.
Analog output: verify current value, High alarm current, and Low alarm current.
See “Analog output verification” on page 28.
