Table 14 STATUS command
Syntax Description
STATUS
<cr> Select at the prompt (
?
) whether the alarm is
enabled or disabled and define the voltage/
current levels.
The following example shows the purge status alarm enabled for channel 1:
status
Channel 1:
Status : ON ?
Level Lo : 0.00 ?
Level Hi : 5.00 ?
Channel 2:
Status : OFF ?
Level Lo : 0.00 ?
Level Hi : 0.00 ?
Level Lo and Level Hi are shared between the STATUS and ALARM commands. For example, if
you change the levels using the ALARM command, they will also change when viewing the
STATUS command.
5.3.3 Malfunction Alarm
If the transmitter is malfunctioning, the channel output is set to a pre-defined level. This
overrides the normal measurement output of the channel. You can specify the level using the
AERR command:
Table 15 AERR command
Syntax Description
AERR
<cr> Enter the error output level at the prompt (
?
)
for each channel.
Example:
aerr
Ch1 error out : 20.000 mA ?
Ch2 error out : 0.000 V ?
The current value is shown after the colon " : ". To set a new value, enter it after the question
mark. The error output value must be within the valid range for the selected output mode.
The error output value is displayed only when there are minor electrical faults
such as a humidity sensor damage. When there is a severe device malfunction,
the error output value is not necessarily shown.
