Data ProCessIng of the oPtICal sIgnal
133
the output signal from
the pre-amplifier is not
stable.
- Photometer lamp is about to burn out- chan-
ge lamp.
- Check the stability of the lamp voltage of
+11V
- Check the stability of the power supply on
TP15 (+ 15V) and TP6 (– 15V) board
17970/19
- Replace the pre-amplifier board.
- False contact or an oxidized connection bet-
ween the lamp connector and the power sup-
ply board 17970/10. Clean with alcohol and if
necessary replace it.
- A leak in the quartz window inside the incu-
bation bath. Replace it and make sure there
are no leaks.
absorbance measurement
using the diagnostic
program varies within ± 2
mabs (out of range)
- Repeat the checks as above
- Execute a [
Water blank
] using filter 340 nm
(filter 1)
- Select the box [ ] to measure Absorbance con-
tinuously at 340 nm
- Click on [
Read one
] to start the measure-
ment. Make sure that the Absorbance mea-
surement is within the specified range of ±
2
mab
s
- Replace photometer lamp
- Align Home + Sync of the Photometer
- Replace board
17970/19
the operating program
signals “fatal eRRoR…“
after having given an in-
termittent acoustic (beep).
probable Cause:
missing SynC signal from
photometer module.
- Check the start up PWR ON voltage of the Cu-
vette System. (See also „3.5 Trouble Shooting
Guide“.)
- Activate rotation of the
filter wheel
and
check the ON/OFF of the LED SYNC on driver
17970/23
- Make a mechanical alignment of the HOME
signal and the SYNC of the Photometer.
- Check the variation from 0V to 5V on pin 3 of
U3 17970/8
- Replace the Opto Sync 17970/13
- Replace board 14970/23
- Replace U3 – 17970/8
