TOPIC 14 PROBE CALIBRATION
Describes how to calibrate the probe sensors. Probe calibration allows the user to calibrate the probe sensors using two
different methods; external and internal. The following screen is displayed when this option is chosen.
The following is a summary of the options available in Probe Calibration.
Select Probes -- Allows the user to select which probes to calibrate. Only used for external and internal probe
calibration.
Calibration Types -- Allows the user to select the calibration method. Only one probe calibration method can be
chosen.
1. External -- Upon selecting this option the External Probe Calibration popup is displayed. In this calibration mode,
the user simply enters a new calibration offset value for each probe selected. It is completely the user’s responsibil-
ity to enter the offset values correctly. A valid offset value is within the temperature range of --2.00_C to 2.00_C.
2. Internal -- Upon selecting this option the Internal Probe Calibration popup is displayed. In this calibration mode, the
user must place the probes to be calibrated into an ice bath. The user then enters the bath temperature to calibrate the
probes. A valid bath temperature value is within the range of --1.00_C to 1.00_C.
3. Automatic -- This is a special case of the Internal calibration in which the probe offsets will be calculated using a
non--changeable water bath temperature of 0.0_C.
Send -- Sends the probe calibration to the recorder. Upon completion the DataView program informs the user that
the probe calibration was successfully sent to the recorder.
Help -- Displays the help screen.
Cancel -- Cancels the probe calibration and returns the user to the System Tools Screen.
