Calibration
Your instrument was carefully tested and calibrated before being shipped from the factory. For greatest ac-
curacy, we recommend factory re-calibration every 6-12 months. Call customer service at (630) 543-3747. If
you wish to do calibration yourself, follow these procedures.
1.
To activate calibration mode, turn the unit on and press and hold both the On/Off button and the Adjust-
Up button (making sure to press the Adjust-Up button first so the unit will not turn off). The led will
blink in amber rapidly for about five seconds, and turn solid green. Release the On/Off button and the
Adjust-Up button, the led will then blink amber at which point only the pen being adjusted will show on
the display.
2.
To raise the unit of measurement, press the Adjust-Down button. To lower the unit of measurement,
press the Adjust-Up button. Pen home switches between the red and blue pens on a two pen unit and
stores the current adjustment value.
3.
When calibration is complete, press the On/Off button. Calibration is stored in memory even after you
turn the unit off. User calibration information will not be lost if AC power fails.
4.
Note: After two hours, if no buttons are pressed, the unit will time out of user calibration and resume
normal operation. The user calibration is stored separately from the factory calibration. If you wish
to cancel out your user calibration, simply enter calibration mode and toggle through the steps without
adjusting displayed readings. Exit by pressing the On/Off button. You have now restored factory
calibration.
Note: It is recommended that you use a controlled chamber when calibrating temperature and humidity.
Calibrating in an open room is not recommended as humidity can vary greatly within a very small area.
