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.
