RDGK? Kelvin Reading Query
Input
RDGK? <input/channel>[term]
Format nn
<input/channel>
Specifies which input or channel to query: A (control input),
1 to 16 (measurement input).
Returned <kelvin value>[term]
Format ±nnn.nnnE±nn
Remarks Also see RDGST? If no curve is present for the channel, the returned reading will be
zero.
RDGPWR? Excitation Power Reading Query
Input
RDGPWR? <input/channel>[term]
Format nn
<input/channel>
Specifies which input or channel to query: A control input),
1 to 16 (measurement input).
Returned <excitation power>[term]
Format ±nnn.nnnE±nn
Remarks Also see RDGST? Returns the most recent power calculation for the specified channel.
RDGR? Resistance Reading Query
Input
RDGR? <input/channel>[term]
Format nn
<input/channel>
Specifies which input or channel to query: A (control input),
1 to 16 (measurement input).
Returned <ohm value>[term]
Format ±nnn.nnnE±nn
Remarks Also see the RDGST? command.
RDGST? Input Reading Status Query
Input
RDGST? <input/channel>[term]
Format nn
<input/channel>
Specifies which input or channel to query: A (control input),
1 – 16 (measurement input).
Returned <status bit weighting>[term]
Format nnn
Remarks The integer returned represents the sum of the bit weighting of the status flag bits. A
“000” response indicates a valid reading is present. If the channel being queried is not
the actively scanning channel, the status will represent the last state prior to the
channel change.
