MVV MV/V CALIBRATION —
Model 3570 DC Strain Gage Conditioner only
MVV=i,u [CMT]
Sets an appropriate SCALING FACTOR for the Model 3570 DC Strain Gage Condition-
er based on "i" (the transducer sensitivity rating in mV/V, full scale) and "u" (the nomi-
nal full-scale rating of the transducer expressed in the desired engineering units and
precision), if excitation = 10 V; when excitation = 5 V, "u" = twice the full-scale rating;
when excitation = 2 V, "u" = five times the full-scale rating). For RS-485 (only), returns
ACK [EOT].
IMPORTANT: THIS COMMAND SHOULD ONLY BE APPLIED WHEN THE 3570 IS SET
FOR "TWO-POINT" OR "CALCULATED" CALIBRATION—THAT IS, WHEN THE
CAL=MXB [CMT] COMMAND IS IN EFFECT. IF ENTERED WHEN CAL=LIN [CMT],
UNPREDICTABLE READINGS COULD OCCUR.
MVV [CMT]
Reads current "MVV" calibration constants. Returns i,u [EOT]. See Section 4.d.4
regarding the answer returned in response to an MVV [CMT] interrogation.
NOD NODE
NOD [CMT]
Reads the NODE NUMBER ("n") of the currently "open" node. Returns n [EOT], where
0 ≤ n ≤ 99. A Node Number can be assigned only through the COM button procedure
given in Section 3.a.3.
OPN OPEN
OPNn [CMT]
"Opens" Network Node No. n (only) for RS-485 communications with the supervisory
computer. There must be no space between "OPN" and the node number n; also, the
node number must not contain a leading zero. For RS-485 (only), returns ACK [EOT].
PEK PEAK
PEK=ON [CMT]
Places the unit in "+PEAK" mode, if Terminal 6 of the rear Logic I/O Connector is at
Logic 0. Disabled when Terminal 6 is at Logic 1. For RS-485 (only), returns ACK
[EOT].
PEK=OFF [CMT]
Places the unit in "TRACK" mode, if Terminal 6 of the rear Logic I/O Connector is at
Logic 0. Disabled when Terminal 6 is at Logic 1. For RS-485 (only), returns ACK
[EOT].
PEK [CMT]
Reads current "+PEAK" status. Returns ON [EOT] or OFF [EOT].
PRI PRINT INTERVAL
PRI=t [CMT]
Sets the automatic print interval to approximately (t x 0.125) second(s), where 0 ≤ t ≤
32700. For no interval, enter a t of "0." For RS-485 (only), returns ACK [EOT].
PRI [CMT]
Reads current automatic print interval setting. Returns t [EOT].
PRN PRINT ENABLE
PRN=ON [CMT]
Enables automatic RS-232 print transmission for the instrument (to be controlled by
front-panel PRINT button or rear logic input when the instrument is in RS-232 mode).
Automatically in effect on powerup. Has no effect on CHN or DMP command. For
RS-485 (only), returns ACK [EOT].
PRN=OFF [CMT]
Disables automatic RS-232 print transmission. Has no effect on CHN or DMP com-
mand. For RS-485 (only), returns ACK [EOT].
