Tip:
To help connect the test leads remove the instrument lid. Open the lid to approximately 45º and slide it to
the right.
Test Lead Connection
A good test measurement requires both the Current carrying circuit and the Voltage detection circuit to be
completed by the unit under test. The Instrument checks for continuity in both C and P circuits.
A test will not start until there is a good connection to the test piece by the test leads.
Confirmation of successful continuity:
„ If C 1----2 and P 1----2 are constant the connectivity is good
„
If either C 1----2 and P 1----2 flash there is no connectivity, and the test will not start
Successful Connection Unsuccessful connection
The resistance result is shown on the display in either Ω, mΩ or µΩ ranging from 2500.0 Ω to 0.1 µΩ.
The result in Bi-directional modes is the average of two readings shown by the two secondary displays, with
arrows to show the direction of current flow. The large arrow at the top of the display between C1 and C2 shows
the measurement current flow.
