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 m
Ω, and voltage is 1.3921 V.
Error
This command causes an execution error if issued during the Continuous Mea-
surement 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 mea-
surement.
• Wait 100 ms before applying the trigger with
:READ? immediately after
changing the measuring conditions during measurement.
See " Measurement Value Formats" (⇒ p.150).
Trigger Source Operation
IMMediate Triggers and reads measured value.
EXTernal
After triggering by the TRIG
terminal (EXT I/O) or TRIG key,
reads the measured value.
