How to Use the Test Tool

Input Connections
The top of the test tool has four safety BNC signal inputs (model 190M-4-III) or two safety BNC
jack inputs and two safety 4-mm banana jack inputs (model 190M-2-III). These isolated inputs
allow independent floating measurements with each input. The banana jack inputs (model
190M-2-III) can be used for DMM measurements or can be used as External Trigger input for the
Scope mode.

Note
To maximize the benefit of independent isolated floating inputs and to avoid problems
caused by improper use, see
For an accurate indication of the measured signal, you must match the probe to the input
channel on the test tool.
When using probes that are not included with the Product, see
Scope
To make scope measurements:
1. Connect the red voltage probe to input A, the blue voltage probe to input B, the gray voltage
probe to input C, and the green voltage probe to input D.
2. Connect the short ground leads of each voltage probe to its own reference potential. See
