Extend Analog Output Range
Use the
AOVER
command to allow the analog output channels to
exceed their specified range by 10%. The scaling of the quantity remains
as before; the extra range is used for additional measurement range in the
wet end. This command is not in use in the digital-only HMP110 probe
option.
AOVER
[
ON/OFF
]<cr>
The following example illustrates how the analog output is affected.
Channel 1 outputs T
d
with voltage output 0 … 5 V (-40 °C … +60 °C).
After giving the
AOVER ON
command, the range is 0 … 5.5 V
(-40 °C … +70 °C). Note that the +60 °C T
d
point is still at 5 V.
Example:

AOVER : ON
Extend Maximum RH Reading
With digital output, use the
RHLIMIT
command to set the maximum
RH reading from 100% (default) up to 120%.
With analog output, the
RHLIMIT
command allows you to extend the
high limit of the analog output scaling up to 120%. This command does
not change the scaling automatically. To change the scaling, use the
ASEL
command (see Set Analog Output Parameters and Scaling on page
RHLIMIT
[
max_rh
]<cr>
where
max_rh
= Maximum reading of the RH parameter. The possible values
are 100.0 … 120.0. The default value is 100.0.
Example (extend the maximum RH reading to 120%):
rhlimit 120
Max. RH % : 120.0 %RH
