E1412A Multimeter Application Examples Keysight E1412A Multimeter Application Information
SYNCHOPC Source Code File
This program has the multimeter take 10 measurements. The Standard Event bit
(ESB) in the status byte (see Figure 2-5) is monitored to detect when the
operation is complete. Readings are transferred to the output buffer by a
FETC?
command and retrieved by the computer following the indication that the
operation has completed. The Multimeter then calculates the average, minimum
and maximum reading.
**** Set up the Multimeter ****
*RST
Reset the multimeter.
*CLS
Clear the multimeter's status registers.
*ESE 1
Enables bit 0 of the multimeter's standard event register.
CONF:VOLT 15
Configure for dc volts, expected input of 15V.
VOLT:DC:NPLC 10
Set number of power line cycles to 10.
TRIG:COUN 10
Multimeter will accept 10 triggers.
TRIG:DEL .01
Use a 10ms delay before each measurement.
CALC:FUNC AVER
Select the math function AVERage.
CALC:STAT ON
Enable math operations.
INIT
Puts multimeter in wait-for-trigger state; trig source is "IMM";
internal trigger occurs "immediately" and measurements are stored
in multimeter internal memory.
*OPC
Waits for all measurements to complete then sets bit 0 in the
standard event register (the operation complete bit)
Loop
SPOLL - read the multimeter's status byte until bit 5 (ESB) goes
high.
