Power On Sequence
The 9600 Plus Calibration Tester receives power from a wall-
mount power pack that plugs into the back of the unit. There is
no ON/OFF switch. On power up, the 9600 Plus Calibration
Tester performs internal self-checks, displays an all-segments
test pattern, beeps and displays the device’s current
temperature. The 9600 Plus Calibration Tester immediately
applies heat, if needed, to reach the selected Calibration Set
Point Temperature.
