What time range of Environmental Temperature Chart Recorder should I use for my trip?

You should use a recorder that will record a long enough time for you longest trips so you do not run out of chart and have missing data. Also you should use a recorder that does not record too much longer than the trip or the resolution will not be good. For example, if you use a 62 Day recorder for a 1 day trip you will only have less than 1 inch of written data which is not good enough resolution to see temperature swings or time accuracy.

What temperature range of Environmental Temperature Chart Recorder should I use?

There are 2 ranges to choose from. Be sure the trip temperatures will be within the recorder range or the stylus will move to the top or bottom of the chart and stop – no longer showing the actual temperature.

What happens if the temperature goes outside the range of the chart recorder?

The stylus will stop at the edge of the range and write at the very top or bottom of the chart until the temperature is within the range then it will continue recording correctly. If the temperature goes below -40°C the chart recorder may stop moving the chart due to low battery voltage then restart when the temperature rises.

What batteries are in the chart recorders?

Standard and High Range: AAA Alkaline

Can the product be used more than once?

Yes. You can purchase more charts and reuse the unit as many times as needed.

I attached the chart to the spool but it does not move.

1. The power switch is off (no LCD readout).
2. The battery is low or is backwards – replace or check the battery position.
3. The chart is not attached to the spool. Tip: Use a 1” piece of scotch tape to attach the chart to the spool to eliminate this problem.
4. Either the drive motor gear or clutch in the barrel (spool) is slipping. Call DeltaTrak Technical Support for assistance.
