LOCAL
Purpose Returns control to the RPM4-E-DWT front panel.
Command “LOCAL”
Classic “LOCAL”
Remark
The REMOTE program message can lock the front panel out completely. The user can return
to local operation by sending the LOCAL program message, sending the IEEE-488 ‘GTL’
command (if in enhanced format), or by cycling RPM4-E-DWT power.
Example
(enhanced) Cmd sent:
Reply: “LOCAL”
“LOCAL”
(no reply if IEEE-488)
Example

MEM
Purpose Read the status from the power-up memory test.
Query “MEM?”
Classic “MEM”
Remarks
The RPM4-E-DWT system memory stores the user settings (units, resolution) and retains
them when the unit is OFF. On power-up, this memory is checked. If this memory is corrupted,
all user settings are reset to default , and the MEM status is set to reflect this.
Example
(enhanced) Query sent:
Reply: “MEM?”
“0” RPM4-E-DWT data corrupted and was set to factory defaults.
“1” The memory was found to be OK on power-up.
Example
(classic) Sent:
Reply: “MEM”
“MEM=0” RPM4-E-DWT data corrupted and was set to factory defaults.
“MEM=1” The memory was found to be OK on power-up.

Remarks The user can select the type of remote command format to use. This format must agree with the
format sent to the RPM4-E-DWT
The enhanced query form of this command (“MSGFMT?
n
