Reactivation frequency
1. Select the ACTIVAT. FREQ option to set the time period between electrode reactivation. When
this time period expires, the electrode is reactivated automatically with an injection of a small
amount of reactivation solution.
2. Set the reactivation mode to either a Frequency or a fixed date.
3. If set to frequency, the recommended time period is 24 hours so that the electrode is reactivated
on a daily basis.
Note: If this value is set to zero, then no electrode reactivation will take place during the calibration process and
as such the calibration may be inaccurate. It is highly recommended to set this parameter to 24.
4. If set to a fixed date, define the day and time of the week when reactivation takes place. Set the
day of the week to an asterisk if reactivation is not to take place on that day.
Datalogger setup
1. Select the VIEW DATA option to display the requested data.
2. All information matching the parameters selected in the VIEW SETUP option is displayed on the
screen. If the data covers more than one screen, an Arrow key will be displayed at the bottom.
Use this key to scroll through the data.
3. Select the VIEW SETUP option to define the parameters for the data you wish to view.
4. The FROM data field is the date (DD/MM/YY) from which you want to start viewing data.
5. The AT data field is the time (HH:MM:SS format) from which you want to start viewing the data.
6. The CH field defines the channel for which you want to view the data.
7. If you wish to see the ALARMS information (both system and warning alarms), select Yes in this
field, or No if alarm information is not required.
Graph time base
For graphical displays, enter the number of hours as the base line for the graph.
