NPACKING AND

mode rather than run mode; see menu below.

plied to the chamber; cycles on and off as heat

tion. Each time you press the Menu button, the
mode changes in this sequence:
• Select temperature units in ºC or Fº(display
shows _C_F).
• Calibrate the unit (display shows CAL).
• Display the actual temperature of the chamber
(normal mode of operation).
• The unit will return to normal operation, dis-
playing the actual temperature, if you do not
touch any control for a few seconds.
Set: When in the normal mode of operation,
allows you to change the temperature setpoint.
When in the _C_F mode, allows you to change
the temperature units displayed. When in the
CALibration mode, allows you to set the temper-
ature offset to calibrate the unit.
Increase: After entering other than normal
mode, increases the displayed value.
Decrease: After entering other than normal
mode, decreases the displayed value.
Safety controller: Sets the Limit temperature
above to the primary setpoint; should be set at a
higher temperature than the setpoint to give the
safety control in the event that the primary con-
trol fails.
