INPUT:OFFSET

The INPut:OFFSet command sets the input threshold for a channel or group of channels, over which the input signal must cross to cause an interrupt event. This command sets the value in the 8-bit DAC to which the input signal is compared. It is important to note that the actual input offset value is affected by the INPut:RANGe command, as the response has been normalized to ±10 V range. The actual input offset for the allowable ranges are as follows:

 

Range
