Installation

Control Box Controls and Indicators

Input Mode Button and LEDs

Press the Input Mode button to select one of
the four TriMode measurements. The modes
cycle in the following sequence:

A – B (for differential signal measurement)

A – GND (for A input single-ended
measurement)

B – GND (for B input single-ended
measurement)

(A + B)/2 – GND (for common mode
measurement)

NOTE.

You can also change the Input Mode

in the oscilloscope Probe Setup screen. (See
Figure 4 on page 25.)
