CHAPTER 4

OPERATION

4.1 Current Measurement

WARNING: Always connect the probe to the instrument before clamping onto the circuit under test.

• Connect the Model SR661 to the proper input channel on theoscilloscope.

• Beginwiththeleastsensitiverangeonthecurrentprobe(1mV/A)

• Selectthe0.5V/Divisionrangeontheoscilloscope.

• Clamptheprobeontheconductortobemeasuredandreadthecurrentflowingdirectlyonyouroscilloscope.

(Remember to unclamp the probe from the conductor before discon-necting it from your meter or instrument.)

You may also use your oscilloscope to amplify the signal while usingthe1mV/Aproberange(whichoffersthebestaccuracyandleastphaseshift).

NOTE: It is possible to change the range on the current probe without remov-ing the probe from the current carrying conductor, but it is important to remember not to exceed the permissible peak ratings of 2000mV peak or 4000 mV peak to peak maximum. The peak ratings by range are: 20A peak @ 100mV/A, 200A peak @ 10mV/A and 2000A peak @ 1mV/A.
