DIAGnostic
DIAGnostic:OTDetect[:STATe]
DIAGnostic:OTDetect[:STATe] <enable>,(@<ch_list>)
enables and disables the
VT1422A's "Open Transducer Detection" capability (OTD). When Open Transducer
Detection is enabled, a very high impedance path connects all SCP channels to a
voltage source greater than 16 volts. If an enabled channel has an open transducer,
the input signal becomes the source voltage and the channel returns an input
over-range value. The value returned is +9.91E+37 (ASCII).

Parameters
Comments
•
Open Transducer Detection is enabled/disabled on a whole Signal Conditioning
Plug-on basis. Selecting any channel on an SCP selects all channels on that SCP
(8 channels per SCP).
(8 channels per SCP).
•
The DIAG:CAL:TARE:MODE <mode> command affects how OTD is controlled
during the CAL:TARE? operation. When <mode> is set to 0 (the *RST Default),
channels are tare calibrated with their OTD current off. When <mode> is 1,
channels that have their OTD current on
(DIAGnostic:OTDetect ON,(@<ch_list>)) are tare calibrated with their OTD
current left on.

*RST Condition: DIAG:OTDETECT OFF
If OTD is enabled when *CAL? or CAL:TARE is executed, the module will
disable OTD. Wait one minute to allow channels to settle, perform the calibration,
and then re-enable OTD.
