Using the Scope and Meter

Input Connections

Look at the top of the test tool. The test tool has four

safety BNC jack signal inputs (models 190–xx4), or two

safety BNC jack inputs and two safety 4-mm banana jack

inputs (models 190-xx2).

Isolated input architecture allows independent floating

measurements with each input.

ALL INPUTS ISOLATED

Figure 5. Measurement Connections

Making Input Connections

To make scope measurements connect the red voltage

probe to input A, the blue voltage probe to input B, the

grey voltage probe to input C and the green voltage probe

to input D. Connect the short ground leads of each voltage

probe to its own reference potential (See Figure 6).

For Meter measurements refer to the applicable section in

this chapter.

Warning

To avoid electrical shock use the insulation

sleeve (Figure 1 item e)) if you use the probes

without the probe tip or the ground spring.

Notes

− To maximally benefit from having

independently isolated floating inputs and to

avoid problems caused by improper use,

read Chapter 6: “Tips”.

− For an accurate indication of the measured

signal, it is necessary to match the probe to

the test tool’s input channel. See section

‘Calibrating the voltage Probes’ in Chapter 7.
