3.1 Important Notes On Calibrator Operation
• The calibrator is a precision instrument. Although it has been designed for
optimum durability and trouble-free operation, it must be handled with care.
• The probe well can be set to very high temperatures. Probes can be very hot
when they are removed from the well. Take precautions to prevent personal
injury to yourself, others and objects in the work area.
• Keep the calibrator connected to the main power source during cool-down
period. If the power switch on the calibrator is turned to the “standby”
position
when the probe well is still hot, a thermal sensor inside the
calibrator will re-activate the cooling fan. The fan will then cycle on and off
until the unit is at a safe temperature for power removal or storage.
• After inserting or removing probes into the probe well allow the calibrator
time to stabilize before making your measurement. Adding or removing
probes changes the total mass of the probe well, the controller will require
time to adjust for this change and stabilize back to the temperature you have
set.

3.2.1 Process Temperature/Setpoint Temperature Display
In the default mode, the display will show the process temperature, i.e. the
probe well temperature. When the modify key is held down, the setpoint
temperature is displayed.
