viii. The unit is now ready for process monitoring.
3) There is no need to adjust the 4mA and 20 mA levels for process
monitoring, unless desired by the user. Instructions for adjusting
the 4mA, 20 mA and display levels are given below
5.4 Initialization for Process Monitoring: Mode 1
Operation
Mode 1 process monitoring is used once a calibration curve has
been developed (see Appendix 1). This initialization sequence requires
that the user generate a process sample with a known analyte
concentration, which is used to calibrate the fluorescence scale.
Outlined below are the steps for initialization of the unit, assuming
that hardware installation and start-up has occurred and that the
Fluorometer is working properly:
1) The fluorescence probe must be immersed in a calibration
sample.
2) Perform Mode 1 initialization.
a) Press the INT PRESET, located in the upper left hand
corned of the Fluorometer , for at least three (3) seconds,
but no longer than five (5) seconds.
b) Both the REF and MSR DET LEDs should have solid
green or flashing green output.
c) Wait 2 minutes for the reading to stabilize.
d) The value on the display should be 1000 ± 20 counts and
the 4-20 mA level should be 12.000 ± 0.164 mA.
e) Insert the span filter using the SPN CHK button located
on the upper end of the Fluorometer housing. When the
filter is in place, the FLTR-IN LED will change from
green to red.
i. Wait 2 minutes for the output to stabilize and the
unit should read an upscale value.
ii. Both the REF and MSR DET LEDs should have
solid green or flashing green output.
iii. If the MSR indicator LED color does change color,
refer to the Diagnostics section below.
