TST?
Purpose
Read the power on self test status.
Syntax
“
∗
TST?””
Remarks
The system memory stores the user settings (units, mode, resolution)
and retains them when the unit is shutoff. On power up, this memory is checked.
If this memory is corrupted, all user settings are reset to default (as if the “
∗
RST”
program message was executed), and the
∗
TST query returns a ‘1’. If the
passed the test on power up OR if the
∗
TST query was used at least
once since the unit was powered up the reply is ‘0’.
Query Reply
“0” or “1”
Example
Command:
Reply:
“*TST?”
“1”
4.3.4.2
commands
#
Purpose
To allow the Host computer to communicate with a device connected to the
COM2 port.
Syntax
“#XX”
Arguments
xx:
The string to send out of the COM2 port. It must be less than
40 characters long.
Remarks
The COM2 port can be used to communicate to another RS232 device
(e.g., another or a multimeter). This allows the user to use one COM
port or IEEE-488 port on the host computer to communicate with the
and another device. A carriage return and a line feed (
<CR><LF>
) are added to
the string.
After this command is issued, the will reply back the first string received
by the COM2 port that is terminated with a carriage return. Line feeds
are discarded. This will discontinue when the next command is sent to the
.
There is no other reply from this command. Prior to using this command, you
must ensure that the COM2 port is correctly set up to communicate
with the device. Refer to the “COM2=“ command.
Example
Command:
Reply:
“#VER”
“FLUKE, molbox RFM Ver1.20”
ABORT
Purpose
To stop an active averaging,
tare
, purge, leak check cycle, or reset the list of gas
calibrations on a molbloc.
Syntax
“ABORT”
Remarks
This command should be used to ensure that in a known state. The
tare
, purge, and leak check cycles put the into a condition where it is
not usable for normal flow measurement, so the “ABORT” command should be
used before general operation of the unit begins if the previous state of the unit is
not known. The “ABORT” command also clears out any previous leak or
tare
cycle errors. If the “GASCALS” command is used to list the calibrated gases on a
molbloc, the “ABORT” command resets the list back to the beginning.
Example
Command:
Reply:
“ABORT”

AIRW(=)
Purpose
Read or set the humidity ratio for the gas, AIR.
Syntax
“AIRW=
HumidityRatio
”
“AIRW”
Default
“AIRW=0.00
00”
Arguments
HumidityRati
o:
The humidity ratio (0-0.1)
Remarks
The humidity ratio is only used if the gas is set to specify AIR. For all other gas
types, the ratio is ignored.
Example
Command:
Reply:
“AIRW=.01”
“0.0100”
Errors
ERR# 6:
The humidity ratio is invalid.
