P983 Start Level
When using automatic simulation this parameter can be used to pre-determine the
point at which the simulated level will start at and return to. This can be used to
simulate the lowest point to which the level would normally operate.
Hardware
P990 Self Test
If you enter 1 for this parameter, then the unit will perform a self-test. This will
confirm that the various parts of the circuitry are working correctly. You will see
confirmation messages that the clock and the EEPROM are working correctly, and
error messages for any parts that fail.
P991 Hard Test
When this parameter is selected, the unit will test the following in turn.
LED’s. Watch them change colour as shown on the display, and press
ENTER if they operated as shown.
Relays. Press a numeric key corresponding to the number of the relay
you wish to test, and the relay will change state each time the key is
pressed. If you press any other key other than a valid relay number then
the test will end.
Keys. You should press each key, to confirm it works, with a counter
showing how many more keys you have to press. Be sure to press the
CANCEL key last, as this will show if all keys were pressed or not. If
they were not, then an error message is displayed.
P992/P993 mA Out 1/2 Test
These parameters will allow you to force a specified current on the mA output to
test the equipment that it is connected to and to make sure the unit is working
correctly. The figure you enter will be generated by the mA output after pressing
the enter key to accept.
P995/P996 Transducer 1/2 Test
If you enter 1 for either of these parameters it will continually fire the transducer,
for 1000 pings, so you can check the wiring. You can cancel at any time during
the test by pressing any key.
