3.4 Controller Parameter Settings
3.4.1 Changing Controller Parameter Settings
The parameters in your calibrator have been set and fine-tuned to provide
the best performance possible from your unit. The unit will operate at its
optimum performance when left with the factory parameter settings. The only
parameter that the operator should change is the temperature setpoint or
displayed engineering units (°F or °C).
Changing any other parameter settings
will decrease the accuracy and stability of your calibrator.
3.4.2 Changing The Temperature Setpoint
The CL1000 incorporates a PID digital setpoint controller. In the default
mode the digital display indicates the probe well temperature known as (PV)
Process Variable. Holding down the modify button causes the display to show
the programmed setpoint known as (SV) Setpoint Variable. Making changes
to the setpoint or units of measurement settings are made by pressing the
(Modify) button in conjunction with the
(Up arrow) button or
(Down
arrow) button. Holding the (Modify) button and (Up arrow)/ (Down
arrow) button for an extended period will cause the setpoint temperature
to advance more rapidly to a desired value. The minimum and maximum
setpoints are locked out at 0 and 260°C (32 and 500°F), respectively.
Do not re-program the controller’s parameter settings or change wiring inside your unit to
override the maximum setpoint value of 260 °C (500 °F). You may permanently damage your
calibrator and cause possible personal injury and/or create a fire hazard.
3.4.3 Changing The Display Units From °C to °F or (°F to °C)
Press and hold the
(Up arrow) and
(Down arrow) buttons on the
controller at the same time for 3-4 seconds, then release. The display will be
flashing between“tune – off”. Press the
(Down arrow) button one time. The
display will be flashing between “LEVEL-1”. While holding the (Modify)
key down press the (Up arrow) button one time. The display will be
flashing between “LEVEL-2”. Now that you are on menu level 2 release the
button. Press the
(Up arrow) button eleven times. The display will now be
flashing between “unit – ºF” or “unit-ºC”. To change the current units setting
press and hold the (Modify) button, then press the
(Up arrow) or
(Down arrow) button one time to change between
units. To save your change and return to the run mode press and hold the
(Up arrow) and
(Down arrow) buttons at the same time for 3-4
seconds, then release.
