5 Characteristics and Specifications
Digital Multimeter Specifications
162 U3606B User’s Guide
[5] Specifications stated are for 4-wire low-resistance measurements. The test current is sent from the FORCE terminals and
the resistance is measured by the SENSE terminals.
The contact strength may influence the measuring result significantly. Ensure that the connection of the test point is firm to
avoid resistance due to contact leads.
The accuracy is specified after source compensation due to environment temperature changes. Initiate the compensation
by exiting and entering the Lo-Ω function or by disabling and enabling the output.
The measuring current will be reduced automatically when the product of the test current and resistance exceed 7.5 V. Refer
to the test current and resistance as shown below:
[6] Specifications stated are for the voltage measured at the input terminals only. The test current (1 mA) is typical. Variation in
the current source will create some variation in the voltage dropped across a diode junction.
[7] Specifications stated are for open test lead measurements and film capacitor or better using the Null math operation.

NOTE
For the total measurement accuracy, add the probe error. The contact strength will
significantly influence to the measuring result. Ensure proper contact at the test point you
want to measure.
