Storing Data - 64
A selection of 10 minutes, for example, will result in the instrument storing a result every 10 minutes. The
instrument will use the Pump Time parameter as it calculates its timings.
For example, if a pump time of 2 minutes and a period of 15 minutes is selected then the pump will be off for 13
minutes, then will operate for 2 minutes so the results are stored every 15 minutes.
Pressing ‘OK’ will scroll through these options. When you have selected the required value, use the ‘Up/Down’
arrows to move to the next parameter.
By default, the Pump Time is 2 minutes and the period is 15 minutes.
12.4.3 Total Logs
These parameters determine the total number of samples which will be taken.
Unlike Pump Time and Period, you can set Total Logs to any number between 0 and 3000 readings. The upper limit
is determined by the remaining store space.
If Total Logs is set to 0 it will Log continually until there is no more store space remaining.
To change Total Logs, select the field and press OK. Then use the Left and Right Key to highlight the digit you wish
to change and use the Up and Down Keys to increment or decrement that number. To move to the next digit, use
the arrow keys again.
Once you have set your Total Logs press OK to move to the next field.
By default, Total Logs is 10.
12.4.4 Bat Save On
The battery save function is on by default and increases the length of time the instrument can be left to perform
unattended data logging by shutting down between samples.
With battery save enabled the instrument will switch itself off 5 seconds after taking a sample unless it is
interrupted, for example by a Key being pressed or the log ending, then switch itself back on approximately 30
seconds before it is due to start taking its next sample.
With battery save disabled the instrument will remain always turned on, until the battery is empty.
