7.0 SETUP
(OPERATION
AND
DIAGNOSTICS)
(<SETUP>
K
EY
)
There are a number of diagnostic screens to monitor the performance of the unit.
7.1
AMPLIFIED SIGNAL <1>
Press the <SETUP> key then Press <1> for AmpSig.
This screen displays the FLR (Sample Fluorescence) and the REF (Lamp Reference) signal values
AFTER amplification. The values when the lamp is ON as well as OFF for both the FLR and the REF
are displayed as well as the respective difference between the ON and OFF values. The OFF values
are typically a measure of the background fluorescence and are therefore subtracted from the ON
values. The bottom line shows the REF value and temperature value at calibration.
7.2
UNAMPLIFIED SIGNAL <2>
Press the <SETUP> key then Press <2> for UnAmpSig.
This screen displays the FLR value (the difference between the ON and OFF values) BEFORE
amplification. This is a calculated value based on the measured amplified signal and the gain value.
The Total Gain, Fixed Gain and Pot (Adjustable Gain) values are also displayed on the same screen.
7.3 DIAGNOSTICS
<3>
Press the <SETUP> key then Press <3> for Diags.
The screen displays the currently applied temperature compensation correction on fluorescence and
lamp reference values.
In addition to the above information, the mA output can be forced to either 4 or 20mA regardless of the
ppm value. Forcing the mA value is useful to check the response or performance of external
equipment such as chart recorders or control devices.
7.4 MIN/MAX
<4>
Press the <SETUP> key then Press <4> for Min/Max.
This screen displays the FLR and REF minimum and maximum values for the last 10 seconds as well
as their difference. These figures give an indication of the reading stability.
7.5 SETTING
<5>
Press the <SETUP> key then Press <5> >, enter the password at the prompt, then press <ENTER> for
Settings.
7.5.1 mA
TRIM
<1>
Press <1> for mA Trim. This procedure trims the mA output for maximum accuracy by compensating
for the mA output circuitry tolerances.
Important:
THIS PROCEDURE IS PERFORMED AT THE FACTORY AND IS TO BE PERFORMED
BY AUTHORIZED PERSONNEL ONLY. IF IMPROPERLY DONE, THE ACCURACY OF THE MA
OUTPUT CAN BE IMPAIRED.
