Example (show present output modes):
amode
Ch1 output : 0 ... 1 V
Ch2 output : 0 ... 1 V
Example (check present analog output error level):
aerr
Ch1 error out: 0.000V ?
Ch2 error out: 0.000V ?
Example (set analog output error level to 1 V on both channels):
aerr
1 1
Ch1 error out: 1.000V ?
Ch2 error out: 1.000V ?
The error output value is displayed only when there are minor electrical faults
such as humidity sensor damage. When there is a severe device malfunction, the
error output value is not necessarily shown.
6.10.4 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 parameter 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
AOVER : ON
6.10.5 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.
