4 THE MENUS WP4C
The WP4C gives you the ability to manually set your instrument
sample chamber temperature. To set your instrument sample cham-
ber temperature, press the lower right button next to the “set T” in
the System Con
guration menu. The following screen will appear:
Adjusting the Setpoint Temperature
Use the buttons next to + and − to adjust the target setpoint tem-
perature (displayed in the lower right corner). If you press either
button it adjusts in increments of 0.1
◦
C.
Note: Holding down the button will rapidly increment the value.
The target setpoint temperature roughly corresponds to the tem-
perature at which you wish the sample to read. Adjust the setpoint
to the temperature that you want, then begin measurements to see
how close your WP4C comes to your desired temperature (this works
best by putting the WP4C in continuous mode). After several sam-
ples, it should show consistent temperature readings. At this point,
make any needed adjustment to the setpoint index number to reach
your desired temperature. You will be able to adjust the index num-
ber between 15 and 40
◦
C. If you press the − button after you reach
15
◦
C, it will disable the temperature control function until you raise
the index number again. When the temperature control is disabled
the display will show ‘off’ in place of the temperature setting.
Important tips with the WP4C
• Before reading, wait for approximately 30 minutes to let the
chamber temperature stabilize after turning it on.
