Single- and multi-stream colorimetric analyzers 10 Diagnostics
54 IM/AZT6CR–EN Rev. J
10.2 Cell Diagnostics
Cell Diagnostics enables the user to control the operation of the analyzer manually – bringing in reagents and sample etc. It also
displays the detector output in real time giving an insight into how the analyzer is performing.
10.3 Relay Test
All of the alarm relays can be set individually or reset to check their operation.
10.4 Current Output Test
Within the Current Output Test Screen the user is able to check the analyzer current outputs manually.
A calibrated ammeter is required for this test. Put the leads from the ammeter onto the two current output terminals on the I/O board
– see Section 4.6.3, page 18.
Check that the value shown on the analyzer LCD is the same value shown on the ammeter.
Use the and keys to increase/decrease the milliamp value.
If the ammeter and analyzer do not agree it may be necessary to recalibrate the current outputs – see Section 6.5.2, page 36.
Note.
If this procedure is selected when the analyzer is in
operation, a warning is displayed:
Note.
Select Back and press to return to normal operation. Select
Continue and press to continue to cell diagnostics. This
stops the current analyzer operation:
Fields Description
Operation Enables the user to bring in solutions, expel solutions or reset the pump.
Volume Enables the user to specify the quantity of liquid (in ml).
Port
Enables the user to specify the port (and therefore liquid) to import. Only one port can be opened at
any one time.
Detector Voltage Displays the detector voltage (0 to 4095 mV) in real time.
LED Current Displays the LED current in real time.
Note. This procedure affects the analyzer relay functions and the analyzer overrides the normal state.
