Oil in Water Analyzer Operation 3
Part I 3-13
Teledyne Analytical Instruments
Every time the power is cycled, the homogenizer defaults to ON. So if
homogenizer was off and the power is cycled, the homogenizer will turn on.
Warning: Do not operate the “ultrasonic homogenizer” in the
instrument for more than one (1) minute without a
liquid sample properly flowing through the homoge-
nizer.
3.3.9 Hold/Track Setup
The 6600 has ability to disable the analog outputs and freeze the display
while undergoing a scheduled or remote calibration. The 6600 will track
changes in the concentration if calibration is started through the front
panel. To setup this feature, the operator must:
1. Enter the System menu:
DIG_FILT SELF-TEST
PWD LOGOUT MORE
2. Using the UP/DOWN switch, select MORE and Enter. The
Second System screen appears:
AUTOCAL HMGNZR TRACK
CAL-HOLDER-TIMER MORE
or
AUTOCAL HMGNZR HOLD
CAL-HOLD-TIMER MORE
3. The option on the right of the first row can be set to TRACK or
HOLD by toggling Enter switch. By selecting the TRACK option, the analog
outputs are enabled and with the display will track the concentration changes
while the instrument is undergoing scheduled or remote calibration (either zero or
span). By selecting the HOLD option, the analog outputs and display are
disabled and will not track the concentration changes while the instrument is
undergoing scheduled or remote calibration (either zero or span). In the HOLD
option, the analog outputs and display will freeze on the last reading before
entering calibration.
The analog outputs are both 0 to 1 volt outputs and both 4 to 20 mA
outputs.
