202 HP E1415 Command Reference
DIAGnostic:OTDetect[:STATe] < enable >,(@< ch_list >)
HP E1415'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).

•
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).
•
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.

Note
*RST Condition: DIAG:OTDETECT OFF
If OTD is enabled when *CAL?, or CAL:TARE is executed, the module will disable
OTD, wait 1 minute to allow channels to settle, perform the calibration, and then
re-enable OTD.
