RUN / CFG Mode – F1 Commands
Note the differences for the F1 • command in RUN and CFG modes.
The Auto-Setup is not used in RUN mode.

F1 • (RUN) — —
F1 • (CFG) Auto-Setup The Auto-Setup optimizes PMT gains and the source lamp currents. Always initiate an
Auto-Setup after any lamps, optical lters, or PMTs have been installed or replaced. For
complete details about Auto-Setup and results, refer to the Auto-Setup information in
Chapter 5. This function is available in CFG mode only.
F1 – — —
F1 0 KFtrz ** Position of the key lter which gives the weakest signal for a given source lamp current,
where ‘z’ (1..2) is the lter being used.
1 = Measure Filter 1
2 = Reference Filter 2
F1 1 Ftrz ** The default source lamp pulse current-control signal (V) for each lter, where ‘z’ = 1..6.
The normal operating range is between 0.5 V and Lamp Max (LampMax typical range is
4.5–7.8 VDC – may vary, check EEPROM Data Sheets for actual value), with the control
signal for the key lter being Lamp Max. If the Ftr value is negative, the lter position is not
used.
1 = Filter 1 4 = Filter 4
2 = Filter 2 5 = Filter 5
3 = Filter 3 6 = Filter 6

for your application, view the Bench Type code (press F2 1 in RUN mode) and
then refer to the Bench descriptions (see “F2 1” under “RUN/CFG Mode – F2
Commands” in this chapter).
F1 2 LmpBz ** The base-current Set Point (V) for each source lamp, which is the minimum operating
current, where ‘z’ = 1..2.
1 = Lamp 1 (closest to the Measuring Cell)
2 = Lamp 2 (farthest from the Measuring Cell)
F1 3 LmpMax ** Voltage to which the lamp pulse current-control signal for the key lter location is set
during Auto-Setup. To ensure a PMT Level of 7.2–7.4 VDC after an Auto-Setup, the Lamp
Max typical range is 4.5–7.8 VDC.
F1 4 PmtLvl ** The photomultiplier tube (PMT) gain control signal (V), which is based on the signal from
the PMT when the key lter is in the light path. Normal values after a successful Auto-Setup
are from 7.2–7.4 VDC. If the PMT Level is not in this range, adjust the Lamp Max and start
another Auto-Setup.
F1 5 PmtBal ** A secondary PMT control signal (V) which adjusts the PMT gain to equalize the PMT sig-
nals when the lters with the lowest and highest transmittances are in the light path. Normal
values after a successful Auto-Setup are from 4.0–7.0 VDC.
F1 6 SigMax ** The signal from the PMT with the highest gain is set to SigMax when each lter is in
the light path while the Auto-Setup is in progress. SigMax should be 8.0–9.0 V (check
EEPROM Data Sheets for actual value).
