∗TST?
Purpose
Read the power on self test status.
Syntax
“∗TST?””
Remarks The molbox RFM 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 molbox RFM 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

“0” or “1”
Example Command:

4.3.4.2 molbox RFM COMMANDS
#
Purpose To allow the Host computer to communicate with a device
connected to the molbox RFM 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 molbox RFM COM2 port can be used to communicate to
another RS232 device (e.g., another molbox RFM or a
multimeter). This allows the user to use one COM port or IEEE-
488 port on the host computer to communicate with the molbox
RFM and another device. A carriage return and a line feed
(<CR><LF>) are added to the string.
After this command is issued, the molbox RFM will reply back
the first string received by the molbox RFM COM2 port that is
terminated with a carriage return. Line feeds are discarded.
This will discontinue when any command is sent to the molbox
RFM.
There is no other reply from this command. Prior to using this
command, you must ensure that the molbox RFM COM2 port is
correctly set up to communicate with the device. Refer to the
“COM2=“ command.
Example Command:
Reply:
“#VER”
