autodelay vs. setdelay

Post by JackRenner » August 18th, 2017, 7:47 am

How do these two settings interact in the 3706A? Does the autodelay setting use the delay specified by setdelay? Or does autodelay use it's own calculation for delay (based on range, measurement type, etc), and then setdelay is added onto that before measurement?

Thank you.

Hi Jack,

The dmm.autodelay setting when turned off, will cause the DMM to take a measurement as quickly as possible without concern of any delays needed based on range, function and other settings. With autodelay turned on, the DMM will wait the time that is necessary for the internal circuitry to settle in order to take an accurate reading. The exact amount of delay that is necessary is dependent on the measurement function and range along with other settings and would be very tedious as a user to have to set yourself. The autodelay setting takes care of this for you.

The channel.setdelay() command sets the amount of delay that will be incurred after closing a channel and before starting to take a measurement. The instrument will delay automatically the required amount of time for the relay to close and any switch bounce to settle out so this setting does not affect the time required for the relay to be solidly closed. This setting is not directly related to the dmm.autodelay setting. However, the two delays are cumulative when switching and making measurements.
