3.3 Changing the Temperature Setpoint
The layout of the front panel is shown in Figure 2. The CL900A/CCL950A
incorporates a PID digital setpoint controller. The setpoint variable (SV) is
changed by holding in either the
key or the key. The setpoint variable
will change at 3 different rates depending on how long a key is being pressed.
The minimum setpoint is 38°C (100°F), the maximum setpoint 482.2°C (900°F).
3.4 Changing the Controller Parameter Settings
The CL900A/CL950A operates at its optimum performance when left with the
factory parameter settings. The only internal parameter that the operator may
need to change is the engineering units (°F or °C). Below are two diagrams: a)
menu hierarchy with factory default settings b) programming procedure. In the
event that some parameters have accidentally been changed, use the factory
default settings shown below.
NOTE:
Changing any other parameter settings besides the engineering units will decrease the
accuracy of your calibrator.

WARNING:
Do not re-program the controller’s parameter settings or change the wiring inside your unit to
override the maximum setpoint value of 482.2°C (900°F).
