SHN SHUNT CALIBRATE—NEGATIVE —
Model 3570 DC Strain Gage Conditioner and
Model 3578 AC Strain Gage Conditioner only
SHN=ON [CMT]
Closes the DC or AC Strain Gage Conditioner's shunt-calibration switch for a negative
up-scale reading. Opens the positive shunt-calibration switch if it is currently closed.
For RS-485 (only), returns ACK [EOT].
SHN=OFF [CMT]
Opens the negative shunt-calibration switch to resume normal measurement. For RS-
485 (only), returns ACK [EOT].
SHN [CMT]
Reads current status of the negative shunt-calibration switch. Returns ON [EOT] or
OFF [EOT].
SHP SHUNT CALIBRATE—POSITIVE —
Model 3570 DC Strain Gage Conditioner and
Model 3578 AC Strain Gage Conditioner only
SHP=ON [CMT]
Closes the DC or AC Strain Gage Conditioner's shunt-calibration switch for a positive
up-scale reading. Opens the negative shunt-calibration switch if it is currently closed.
For RS-485 (only), returns ACK [EOT].
SHP=OFF [CMT]
Opens the positive shunt-calibration switch to resume normal measurement. For RS-
485 (only), returns ACK [EOT].
SHP [CMT]
Reads current status of the positive shunt-calibration switch. Returns ON [EOT] or
OFF [EOT].
TAR TARE
TAR=ON [CMT]
Places the 3500 instrument in "TARE" mode, if Terminal 5 of the rear Logic I/O Con-
nector is at Logic 0. Disabled when Terminal 5 is at Logic 1. For RS-485 (only), returns
ACK [EOT].
TAR=OFF [CMT]
Returns the 3500 instrument to display of "untared" data, if Terminal 5 of the rear Logic
I/O Connector is at Logic 0. Disabled when Terminal 5 is at Logic 1. For RS-485 (only),
returns ACK [EOT].
TAR [CMT]
Reads current "TARE" status. Returns ON [EOT] or OFF [EOT].
TRR TARE REGISTER
TRR=v [CMT]
Sets the TARE REGISTER value to v (-32700 ≤ v ≤ 32700). For RS-485 (only), returns
ACK [EOT].
TRR [CMT]
Reads current TARE REGISTER value. Returns v [EOT].
TYP TYPE — Model 3510 Thermocouple Conditioner only
TYP=y [CMT]
Sets the THERMOCOUPLE TYPE to "y" (where y = E, J, K, R, S, T, or B) and enables the
Model 3510 Thermocouple Conditioner's internal cold-junction reference. For RS-485
(only), returns ACK [EOT].
TYP=y,N [CMT]
Sets the TC TYPE to "y" (where y = E, J, K, R, S, T, or B) and disables the internal cold-
junction reference. For RS-485 (only), returns ACK [EOT].
TYP [CMT]
Reads current TC Type and cold-junction status. Returns y [EOT] or y,N [EOT].
