Applications

Monitor dc level and ac ripple of power supply Troubleshoot amplifier circuits

Check power supply load regulation

Monitor UUT current draw and circuit voltages

Monitor loop current and voltage drop across transmitter

Line and load regulation tests

dc/ac or ac/dc converters

Line and load regulation tests

dc/ac or ac/dc converters

Line and load regulation tests

Transformer (magnetic circuit) saturation

Measure ac amplitude and frequency for line voltage and ac signal analysis

Measure frequency response of an amplifier

Adjust ac motor control

Read noise in telecommunication applications

Adjust portable power generator to optimize power output

Set frequency compensation for a network

Use in "print-only" mode (see "RS-232 Print- Only Mode" in Chapter 5) for quick Bode plots (frequency vs. amplitude)

Test frequency response

Measure ripple and dc current draw of switching power supply

Measure current dissipation in protective fuse resistors used in power supplies

Measure ripple and noise on a line

Show the minimum or maximum value recorded and the present measurement

Show actual measurement and the difference between this value and the relative base.

Select and sort resistors. (See also "Using the Compare Function" in Chapter 3.)

Show actual measurement while holding a previous, stable measurement on the primary display
