pressing any of the buttons on the keypad. If the unit is
locked up there will be no response to button presses
and the Chart Recorder may appear to be working, but
the readings won’t change. Also, the chart will not
rotate. Remove power and battery, and then re-power.
Why don’t the display and chart match?
• Dip switches are set for a specific range, but using
chart for another range, or vice versa.
• Pen(s) not inserted on pen arm(s) all the way
• To adjust pen to match chart see
Pen Adjust
in the
Need to Know
section of this manual.
Note: KT800
does not have a display.
Why does the display read PROB?
• Check the K-TC probe. Make sure it is properly
plugged into the back of unit.
• Is the unit “locked up”? This can be confirmed by
pressing any of the buttons on the keypad, if the unit
is “locked up” there will be no response to button
presses and the unit may appear to be working,
but the readings won’t change. Also, the chart will
not rotate. Remove power and battery, and then
re-power.
Why does calibration seem to be off?
• What is the tolerance of the unit it’s being compared to?
• It’s ok if the unit is within the sum of the two
tolerances.
• Has an outside calibration house attempted
calibration? It may not have been adjusted properly.
• Walk through calibration adjustment, found in
the manual
Why won’t the battery backup work?
• Are there good batteries in the Chart Recorder?
• Keep in mind that battery backup varies significantly
depending on temperature, pen movement and chart
rotation speed.
• If there was a momentary power outage (brown out),
the unit may not have had enough time to recognize
this and switch to
Battery Mode
. (The Chart Recorder
may lock up or shut off in this situation) This situation
may also occur if the unit is plugged into an outlet
that shares the circuit with other machinery that has
phase motors or compressors that cycle periodically.
As these other machines cycle, they momentarily have
a high current draw, therefore drawing from the unit.
Note:
KT800
does not have a battery backup.
Why won’t the chart recorder respond to changes?
• Is the unit “locked up”? This can be confirmed by
pressing any of the buttons on the keypad. If the
unit is locked up there will be no response to button
presses and the unit may appear to be working,
but the readings won’t change. Also, the chart will
not rotate. Remove power and battery, and then
re-power.
Why won’t the unit power up?
• Remove the batteries and power adapter for a
minute or two, this will reset the unit. The unit should
respond when the adapter is plugged in.
Water is getting inside the case.
• Check the battery cover to make sure it is screwed
down tightly at all 5 points.
• Check the case door and make sure it is securely
fastened at both latches.
• Try greasing the door and battery cover gaskets with
a silicone rubber grease.
If the unit is over a year old and/or the door and cover
are frequently opened and closed, we recommend
replacing the door and battery cover gaskets. Contact
