HF scientific AccUView UV %Transmission Monitor - Manual (Page 28)

7.15 Desiccant Alarm
When the humidity detector in the AccUView indicates that the internal environment is
close to the point where humidity could cause condensation, the instrument will display
DESC as a warning. If desired, a desiccant warning can activate the alarms and send the
4-20mA to 2mA. To activate the alarms when the desiccant fails, select On in the DESC
menu. The default for this menu is OFF. Make selections using the
t and u buttons then
press the
↵ button to move to return to AUTO mode.
7.16 4mA Adjustment
If the 4-20 mA setting is turned ON (7.2 Setting the 4-20 mA Output), the following two
menus will appear. The first menu outputs a constant 4 mA while allowing for a small
amount of adjustment. The adjustment can be made using the S and T buttons. This
adjustment will allow the operator to make the AccUView agree with a PLC or SCADA
system. The adjustment limits are ± 200 counts or about ± 0.2 mA.
This setting will be slightly different on each instrument as each AccUView will be
factory set to 4.00mA. Press the
↵ button when adjustments are complete to save this
setting and move on to the 20mA adjustment.
7.17 20mA Adjustment
This menu operates similar to the previous menu. This menu outputs a constant 20 mA
while allowing for a small amount of adjustment. The adjustment can be made using the
S and T buttons. The adjustment limits are ± 1000 counts or about ± 1 mA.
This setting will be slightly different on each instrument as each AccUview will be factory
set to 20.00mA.
