Hardware<br />
P990 Self Test<br />
If you enter 1 for this parameter, then the unit will perform a self-test. This<br />
will confirm that the various parts of the circuitry are working correctly.<br />
You will see confirmation messages that the clock and the EEPROM are<br />
working correctly, and error messages for any parts that fail.<br />
P991 Hard Test<br />
When this parameter is selected, the unit will test the following in turn.<br />
• LED’s. Watch them change colour as shown on the display, and<br />
press, ENTER, if they operated as shown.<br />
• Relays. Press a numeric key corresponding to the number of the<br />
relay you wish to test, and the relay will change state each time the<br />
key is pressed. If you press any other key, other than a valid relay<br />
number, then the test will end.<br />
• Segments. All the segments on the LCD are lit up, so you can see<br />
if they all work. Press, ENTER, to end the test. The LED’s all go<br />
green at the same time.<br />
• Keys. You should press each key, to confirm it works, with a<br />
counter showing how many more keys you have to press. Be sure<br />
to press the CANCEL key last, as this will show if all keys were<br />
pressed or not. If they were not, then an error message is displayed.<br />
P992 mA Out Test<br />
This parameter will allow you to force a specified current on the mA output,<br />
to test the equipment that it is connected to, and to make sure the unit is<br />
working correctly. The figure you enter will be generated by the mA output.<br />
P993 mA In Test<br />
This parameter will allow you to test the mA input, by injecting a known<br />
mA signal from an external source you can check the unit is working<br />
correctly and as expected.<br />
P994 Transducer Test<br />
If you enter 1 for this parameter it will continually fire the transducer, so<br />
you can check the wiring, until you press any key to cancel.<br />
