Performing Measurements and Tests

8 U1273A/U1273AX Quick Start Guide

LPF measurements:

• Passing the measured signal through a LPF help blocks

unwanted voltages such as electronic noise.

• Use the LPF function to improve measurement on compos-

ite sine waves that are typically generated by inverters and

variable frequency motor drives.

LOW

measurements:

• Use the Z

LOW

(low input impedance) function to remove

ghost or induced voltages from your measurement.

• Z

LOW

can remove ghost voltages from your measurements

by dissipating the coupling voltage. Use Z

LOW

to reduce the

possibility of false readings in areas where the presence of

ghost voltages are suspected.

Press while performing ac

voltage measurements to pass the

measured signal through a low pass

filter.

Rotate the rotary switch’s position to

to enable low impedance mea-

surements.
