PGA-710B Autoanalysis System
“ Sampling Rate ” Read bu on. The Read window
will display the computer’s current sampling
rate.
4. To change the sampling rate, click the drop
down menu arrow as seen in Figure 21:
a. Highlight the desired rate, i.e., 50, 100 or
200 samples per second
b. Press Set
c. Press Done in the Device Control window to
complete the sampling rate change.
J. Temperature & Rela ve Humidity Sensor Factory Calibra on &
Adjustments
To ensure the sensor is opera ng based on factory design and ini-
al calibra on, all adjustments or bias must be “cleared” from the
sensor. To “clear” the so ware se ngs:
1. From the Edit drop down menu, select Device Control (See
Figure 22)
2. Con fi rm the Humidity (Rh%) Value window is set at
0.0, and click Clear
3. Con fi rm the Temperature (F) Value window is set at
0.0, and click Clear
4. Click Done to close the window.
Once sensors are reset, use a calibrated temperature and
humidity instrument as a reference to set the appropri-
ate bias for the most accurate temperature and humidity
mesasurements. Follow the instruc ons below for sr ng
temperature and humidity bias.
K. Crea ng a Temperature or Rela ve Humidity Bias
If an acceptable temperature and humidity instru-
ment is available, the PGA-710B’s sensor can be
opera onally adjusted to approximate the reference
as follows (See Figure 23):
1. From the Edit drop down menu, select Device
Control
2. Enter the reference humidity in the Value win-
dow and click the Set bu on
3. Enter the reference temperature in the Value
