Tenma 72-6851 & 72-6853 Instruction manual
Each query produces a specific
<RESPONSE MESSAGE>
which is listed along with the command in
the remote commands list.
<WHITE SPACE>
is ignored except in command identifiers. e.g. '*C LS' is not equivalent to '*CLS'.
<WHITE SPACE>
is defined as character codes 00H to 20H inclusive with the exception of the NL
character (0AH).
The high bit of all characters is ignored.
The commands are case insensitive.
Command List
This section lists all commands and queries implemented in this power supply. Those marked (
†
)
are not available under RS232 control.
Note that there are no dependent parameters, coupled parameters, overlapping commands,
expression program data elements or compound command program headers and that each
command is completely executed before the next command is started.
The following command sections use the following nomenclature:
<pmt>
<PROGRAM MESSAGE TERMINATOR>
<rmt>
<RESPONSE MESSAGE TERMINATOR>
<nrf>
A number in any format. e.g. 12, 12.00, 1.2 e1 and 120 e-1 are all accepted as the
number 12. Any number, when received, is converted to the required precision
consistent with the use then rounded up to obtain the value of the command.
<nr1>
A number with no fractional part, i.e. an integer.
<nr2>
A number in fixed point format, e.g. 11.52, 0.78 etc.
Common Commands
The commands in this section are those specified by IEEE Std. 488.2 as Common commands. All
will function when used on the RS232 interface but some are of little use.
∗
CLS
Sequential command.
Operation complete message generated immediately after execution.
Clear status. Clears the Standard Event Status Register, Limit Event Status Register,
Query Error Register and Execution Error Register. This indirectly clears the Status
Byte Register.
∗
ESE <nrf>
Sequential command.
Operation complete message generated immediately after execution.
Set the Standard Event Status Enable Register to the value of <nrf>. If the value of
<nrf>, after rounding, is less than 0 or greater than 255 an execution error is generated
and error number 119 (out of range) is placed in the Execution Error Register.
