range.
[2] Relative to calibration standards.
[3] Any current measurement greater than 500 mA will have a temporary thermo-effect. If you wish to measure a lower current
or offset current immediately after a high current measurement, ensure that the U3606A has cooled down.
[4] Specifications stated are for 2-wire resistance measurements using the Null math operation. Without Null, add a 0.2 Ω error.
To eliminate the noise interference, which might be induced due to the test leads, a shielded test cable is recommended for
measuring resistance above 100 kΩ.
[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.
[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.
For the total measurement accuracy, add the temperature probe error. The contact
strength will significantly influence to the measuring result. Ensure proper contact at the
test point you want to measure.
