sample chamber can be set from 10 - 50 Deg. C. (40 -122 Deg. F.) and will operate
automatically at the factory default setting unless reprogrammed. If enabled, the AT
SETPOINT will appear in the lower right portion of the main display.
SYSTEM: Time and date on the main display can be changed here. Time is
programmed in 24 hour time, but displayed in 12 hour time, showing AM or PM.
Note: The Time information does not advance while you are in Programming
mode. Therefore, it is recommended that the Time be set last, just before you
press ESC to return to normal mode.
DISPLAY: Parameters to be viewed on the main display, left, center or right, can be set
in any order. Enter a display box: L, C or R, and use the up or down arrows to choose a
parameter (or select NONE). Then press the ENTER key.
ANALOG OUTPUT: The Analog Output is located on the Panel. It can be programmed
to track dew point (DP), ambient temperature (AT), or relative humidity (RH).The low
and high ends of the range are programmable. The output is factory set at 0-5 VDC. 4-
20ma output can be selected from the main circuit board inside the RH-CAL. See the
Maintenance section.
ABC CYCLE: The Automatic Balance Cycle (ABC) can be initiated manually at any
time or started at any specified time of day (ABC START) and repeat at regular intervals
(ABC INTERVAL). The analog output can be programmed to track or HOLD the
parameters during an ABC cycle and the alarm is automatically disabled. If ABC HOLD
is ON, the analog and serial outputs will be held at the values just prior to initiating the
ABC cycle. The display will contain the me
ssage “ABC HOLD”. The hold will be
released when the ABC cycle is complete and the instrument has stabilized back on the
dew point.
SERIAL OUTPUT: To access the serial port it is necessary to have the enable ON and
to select the appropriate baud rate.
FACTORY RESET:
Selecting and pressing the FACTORY RESET field on the Menu
will reset all setup parameters to Factory Default Settings.
