Table 14 – Duoprobe Calibration Parameters - MultiTrode MultiSmart Installation & Operation Manual

The Min and Max pressures, (90 and 140 kPa respectively) that appear at the bottom of the DuoProbe
Pressure Configuration screen represent the pressure range of the DuoProbe pressure sensor and hence
should not need to be modified.
Follow the sensitivity settings for the normal probe to configure the DuoProbe advanced sensitivity
parameters (Refer to Section 14.8.5). The sensitivity settings of Probe 1 are applicable to that of the
DuoProbe 1 and the sensitivity settings of Probe 2 are applicable to that of the DuoProbe 2.
Refer to Section 14.8.4 for more information on configuring the mode of the digital inputs used for the
DuoProbe and for details on configuring it to be able to operate with less than 10 digital inputs.
NOTE: DuoProbe requires at least 3 sensors wired to the digital inputs and hence in cannot be
configured to work like a normal probe in single sensor mode.
There is an option to manually re-calibrate the DuoProbe. This is done in the DuoProbe Model Selection
screen (Figure 114 – DuoProbe Model Selection above). It is highly recommended to clean the probe before
triggering a recalibration, since this will result in more accurate calibrations.
Pressing the Calib button marks the DuoProbe for re-calibration and it will re-calibrate when normal
calibration conditions are met.
In addition to manual re-calibration, a DuoProbe can be re-calibrated using a timer. The timer can be
configured in the advanced screen at:
The DuoProbe Calibration timer has the following configuration settings:
Name
Enabled?
Period Type
Period
Start Time
Table 14 – DuoProbe Calibration Parameters
There is an option to define an additional level (default 10%) to apply to activation setpoints during a
calibration cycle. This is to avoid calibration at the normal lead pump activation setpoint, which is where most
fat build-up is likely to occur. This tag is called Level Adjustment and can be changed at
During a manual or periodic re-calibration, the main operator screen (the home page) displays a flashing
CALIB indication in the level bar graph to indicate that a DuoProbe calibration is pending and setpoints may
be adjusted for the calibration. Once the calibration is complete and setpoints are reset to the original values,
the level bar graph is set to its original state.

Description
Enables or disables periodic DuoProbe re-calibration.
Period Type defines the frequency of DuoProbe re-calibration. It can be re-calibrated
hourly, daily, weekly or monthly.
Period defines the period of the timer. For e.g.: if the Period Type is weekly and
Period is 2, then the DuoProbe will be re-calibrated once in every 2 weeks.
Start Time defines the time of the day at which re-calibration will start.
