On/Off
The ON/OFF key turns the unit on and off. Alarm
and calibration settings are restored to the most
recent values when the unit is turned on. If the
unit is using AC power and power fails, the unit
will switch to battery power without interrupting
the recording capabilities. If power fails when the
battery is not present, the pen will remain on the
chart in recording position.
Pen Home (also Down Arrow)
If the pen is located outside the chart, press the
HOME key to move pen to recording position. Press
the HOME key with the pen in recording position,
and the pen will move to the outside of the chart
and up the pen lift ramp (home).
The PEN HOME key is also used as a down arrow
key to decrease values when setting alarms or cali-
bration values.
Chart Rotation (also Up Arrow)
The CHART ROTATION key sets the chart to the
desired time setting. Press the CHART ROTATION
key to rotate chart. Continue pressing until the
chart reaches the desired time setting. (The red pen
aligned with the timing clip on the 1 thermocouple
unit and the blue pen aligned with the timing clip
on the 2 thermocouple unit.) The chart rotation will
reach full speed after a few seconds holding down
the key. Do NOT attempt to rotate the chart
manually. The CHART ROTATION key is also used
as an up arrow key to increase values when setting
alarms or calibration values.
Alarm (Optional)
The ALARM key turns the alarm on or off. When
the alarm is on the display will flash the MAX &
MIN indicators. Holding the ALARM key for 2
seconds will cause the unit to enter into the alarm
set mode. For a visual alarm the display will read
MIN if a minimum alarm is activated or MAX if the
maximum alarm is activated. The alarm condition
will also trigger an audio alarm if the audio alarm is
enabled (dip switch #8 is off). The alarm will sound
until it is disabled, or until the alarm condition no
longer applies.
