Execute a Measurement and Read the Measured Values
Syntax
Query
:READ?
Response <Measured resistance (NR3)>, <Measured voltage (NR3)>
(
ΩV mode)
<Measured resistance (NR3)>(
Ω mode)
<Measured voltage (NR3)> (V mode)
Description Query Switches from the Idle State to the Trigger Wait State, then
reads the next measured value. With auto-ranging enabled, the
most suitable range is selected before measurement.
Example
Query
:READ?
Response
289.68E-3, 1.3921E+0 (ΩV mode)
Measured resistance is 289.68 mΩ, and voltage is 1.3921 V.
Error This command causes an execution error if issued during the Continuous
Measurement state (after
:INITIATE:CONTINUOUS ON).
Note • The next command does not execute until measurement is finished.
• When the trigger source is external, the ∗
TRG command does not trigger
measurement.
See Section 7.6.3 Measurement Value Formats (Page 141).
Trigger Source Operation
IMMediate Triggers and reads measured value.
EXTernal
After triggering by the TRIG
terminal (EXT I/O) or TRIG key,
