3.2 Re-scaling One or Both Pens on Chart Paper
You can re-scale one or both pens to any range within the operating input range.
Here are the commands:
NOTE
The rescaling of the Temperature Pen is based on Degree F
scale on both CTXL-TRH and CTXL-DTC Models.
Command Description Example
PUT Change Chan 1 Pen (Temp) PUT90; Pen Scale set
top chart value
PUB Change Chan 1 Pen (Temp) PUB50; Pen Scale set
bottom chart value
PLT Change Chan 2 Pen (Humidity) PLT80; Pen Scale set
top chart value
PLB Change Chan 2 Pen (Humidity) PLB40; Pen Scale set
bottom chart value
PR0 Issue the new Pen scales values PR0; Rescaled
to the recorder
PS Get the Pen scales for PS;0090,0050,0080,0040
Chan 1 & 2
PR1 Re-scale the Pens to the PR1; Rescaled
standard Factory scales
In the above example, we are re-scaling both Pens as follows:
Temperature Pen: 50 to 90ºF (Standard: 0 to 120ºF)
Humidity Pen: 40 to 80% RH (Standard: 0 to 100%RH)
After issuing the PR0 command, the new Pen scale values will take affect, otherwise
the previous scale values will remain. The Chart icon comes on to indicate new chart
scale. The new scale is stored in the non-volatile memory. To restore the Pen scales
back to the Factory settings, you need to issue the PR1 command.
The rescaling value can be a negative number on model CTXL-DTC. For example,
you can issue a PC command: PUB-100 meaning the bottom of chart for channel 1
starts at -100.
