Single-Point Temperature Calibration Procedure
1.) Install a temperature reference as close as possible to the HygroClip
©
sensor.
2.) Using a special cable from PGC (Part Number 1609-866), connect the HygroPalm
©
to ACE pc board at the two-pin connector in the upper left-hand corner, labeled DIO.
It is important to note that as long as the HygroPalm
©
is connected to the ACE pc
board, the chamber controller cannot communicate with the HygroClip
©
; therefore,
it is important make the calibration adjustment as quickly as possible.
3.) Press the HygroPalm
©
down arrow key until the display indicates “PROBE 2”. The
display should indicate the temperature and Rh measured by the HygroClip
©
in the
air handler/chamber. If the display does not indicate the measured temperature and
Rh, check the cable connection
4.) Press the MENU key. The display will indicate “CALCULATE”
5.) Press the down arrow ↓ key until the display indicates “ADJUST 1 PT.”
6.) Press ENTER. The display will indicate “RHS”.
7.) Press the down arrow key until the display indicates “Temperature”.
8.) Press ENTER. The display will indicate the current measured temperature. Press the
UP or DOWN ARROW keys until the measured temperature matches the
temperature measured by the reference standard.
9.) Press ENTER. The display will respond “sure?”. Press ENTER again to enter the
calibration offset.
10.) The display will respond “wait” until the data written to the HygroClip
©
.
11.) When “wait” disappears, you can press ENTER to return to the measured value
display screen.

6.) Press ENTER. The display will indicate “RHS”.
7.) Press the down arrow key until the display indicates “Humidity”.
8.) Press ENTER. The display will indicate the current measured relative humidity.
9.) Press the UP or DOWN ARROW keys until the measured Rh matches the Rh
measured by the reference standard.
10.) Press ENTER. The display will respond “sure?”. Press ENTER again to enter the
calibration offset.
11.) The display will respond “wait” until the data written to the HygroClip
