Example: ALAR:RHUM1:LOW:LIM?
Response: 20.00
The RHUMidity suffix, <chn>, specifies the channel (1 or 2). Specifying the
MIN, MAX, or DEF parameter returns the minimum, maximum, or default
value respectively.
8.2.1.22 ALARm:RHUMidity<chn>:LOWer:LIMit <float>|MIN|MAX|DEF
Sets the lower humidity alarm limit for the specified channel in %RH.
Example: ALAR:RHUM1:LOW:LIM 25.00
The RHUMidity suffix, <chn>, specifies the channel (1 or 2). The <float> pa
-
rameter specifies the value for the lower humidity alarm limit. Specifying the
MIN, MAX, or DEF parameter sets the lower humidity alarm limit to the mini
-
mum, maximum, or default value respectively. This command may be pass-
word protected (see Section 8.2.10 , Password Commands).
8.2.1.23 ALARm:RHUMidity<chn>:RATE?
Indicates whether a humidity rate alarm event has occurred for the specified
channel.
Example: ALAR:RHUM1:RATE?
Response: 1
The RHUMidity suffix, <chn>, specifies the channel (1 or 2). A value of 1 is
returned if a humidity rate alarm event has occurred on the specified channel. A
value of 0 is returned if a humidity rate alarm event has not occurred on the
specified channel.
8.2.1.24 ALARm:RHUMidity<chn>:RATE:ENABle?
Returns the state of the humidity rate alarm enable for the specified channel.
Example: ALAR:RHUM1:RATE:ENAB?
Response: 0
The RHUMidity suffix, <chn>, specifies the channel (1 or 2). A value of 1 is
returned if the humidity rate alarm is enabled. A value of 0 is returned if the
humidity rate alarm is disabled.
8.2.1.25 ALARm:RHUMidity<chn>:RATE:ENABle <bool>
Sets the state of the humidity rate alarm enable for the specified channel.
Example: ALAR:RHUM1:RATE:ENAB 1
The RHUMidity suffix, <chn>, specifies the channel (1 or 2). The <bool> pa
-
rameter turns the humidity rate alarm enable on (1 or ON) or off (0 or OFF).
