Why isn’t the chart keeping time or running slow?
• The chart may be hung up or restricted, possibly
caused by a rip on the outer edge of the chart
or the CHART HUB, or the chart may be caught
between the arm and pen(s) arm platform.
• Incorrect chart installed for the selected chart
speed.
Why did the chart stop turning?
• Chart hung up or restricted, (ripped chart)
• Unit may be “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 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 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(s) to match chart see “PEN HOME
Adjust” section of this manual.
Why does the display read PROB?
• Check the sensor pod and KTC probe(s). Make
sure it is properly plugged into the 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 back-up 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.
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
batteries, 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.
