Capacitance calibration
Tube Leak Detection (TLD) operation is based on capacity
measurement at pump head. Once the ambient (base)
capacitance is set by the calibration feature, that value is the 0
point in the scale and then there is a 1-40 trigger level setting
that spreads the sensing range across those settings. The
default setting above the base capacitance is [12]. Depending
on how capacitive the fluid is this can be raised or lowered to
tune the trigger sensitivity.
Examples when Ambient Capacitance should be calibrated:
1. Changes to the pump head or tube configuration.
2. Changes in the application installation location or
conditions.
User Selects ‘Yes’ and presses [ENTER] to calibrate and the
pump responds by reading the capacitance readings from
the sensor. Once that level is read (e.g. 100ms) the pump
will assign the base capacitance level as this value [+] 30ms
to avoid false trigger levels. This level is set as the baseline
capacitance.
NOTICE: Check Set Trigger Level after calibration.
NOTICE: It is recommended to ensure proper leak
triggering that the sensor be tested with a small amount
of actual process chemical. This will help with fine tuning
the trigger sensitivity. All safety precautions and proper
personal protection equipment should be used when
working with corrosive fluids.
