3.3 USING THE INSTRUMENT WITH 2 SENSORS
The instrument can be operated with either one or two sensors connected. Access to the individual displays
can be made using the key. Using this key will focus on one of the two sensors, thus providing a primary
and secondary display (as shown below). The primary display will be shown over half of the screen, with the
secondary display appearing in the opposite corner.
Access can now be gained to the parameters for the primary sensor. The menu options will now move over
to the primary sensor and allow operation to take place as normal.
The secondary sensor will not be disabled automatically and will continue to measure.
3.4 OPERATING THE INSTRUMENT WITH 1 SENSOR
The instrument has the facility to disable the secondary display, allowing the the use of 1 sensor only. This can
be achieved by entering the INSTRUMENT SET UP and setting the SECONDARY CHANNEL option to
OFF using the keys. The instrument will now only show the primary sensor details.
NOTE: This will be globally disabled.
3.5 ENDPOINT DETECTION
The endpoint detection facility can be altered to suit the requirements of individual tests being carried out on
very slow reacting chemicals.
To change the endpoint detection enter the INSTRUMENT SETUP mode and highlight the ENDPOINT
SUPPRESS option. The value may be adjusted by selecting the required time, in units of seconds (1-999),
using the arrow keys and then press .
The instrument will not show the endpoint symbol until the selected time has elapsed. The time entered is
shared time on both channels i.e. it applies to both simultaneously.
