7200 Monitor Instruction Manual
8.7 Take Sample
The Take Sample and Enter Sample Result facilities are
provided to allow calibration to be carried out
retrospectively based upon stored information. An
example of this is where the value of the calibration
solution is not known at the time of calibration and an
estimated value was used to set the instrument span.
The take sample menu is used to store the sensor
signal in the calibration solution for later use.
From the Calibration menu, select Take Sample and press the OK key. With the sensors immersed in the calibration
solution, (The display value must be stable – this can be checked when in measure mode) press the OK key. The
7200 Monitor collects data for the take sample operation for approximately 5 seconds; during this period do not move
the sensor. If the take sample process is successful, the monitor will return to measure mode. If a problem occurs
during the zeroing operation, an error message will be displayed and the monitor will return to the Calibration menu.
8.8 Enter sample Result
When the take sample operation has been carried out, and the correct value for the calibration solution is known, the
new calibration value can be entered using the Enter Sample Result menu.
To enter the new calibration value, from the calibration menu, select the Enter Sample Result menu and press the OK
key. The calibration value can be set to a value between 10 – 100% of the currently selected measuring range using
the

keys. This value should be set to the value of the calibration solution. Once the correct value has been set
press the OK key. Pressing the MENU key will exit the Set Span operation.
Note: The calibration value can only be set between 10 –100% of the display range.
