Simplified Programming Overview

You can program the multimeter to take measurements from the remote interface using the following simple seven-step sequence.

1.Place the multimeter in a known state (often the reset state).

2.Change the multimeter’s settings to achieve the desired configuration.

3.Set-up the triggering conditions.

4.Initiate or arm the multimeter for a measurement.

5.Trigger the multimeter to make a measurement.

6.Retrieve the readings from the output buffer or internal memory.

7.Read the measured data into your bus controller.

The MEASure? and CONFigure commands provide the most straight- forward method to program the multimeter for measurements. You can select the measurement function, range, and resolution all in one command. The multimeter automatically presets other measurement parameters (ac filter, autozero, trigger count, etc.) to default values as shown below.

MEASure? and CONFigure Preset States

Command			MEASure? and CONFigure Setting
AC Filter	(DET:BAND)		20 Hz (medium filter)
Autozero	(ZERO:AUTO)		OFF if resolution setting results in NPLC < 1;
			ON if resolution setting results in NPLC ≥ 1
Input Resistance (INP:IMP:AUTO)			OFF (fixed at 10 MΩ for all dc voltage ranges)
Samples per Trigger (SAMP:COUN)			1 sample
Trigger Count		(TRIG:COUN)	1 trigger
Trigger Delay		(TRIG:DEL)	Automatic delay
Trigger Source (TRIG:SOUR)			Immediate
Math Function (CALCulate subsystem)			OFF
