1. 20% over-range on all ranges, except for 1000 V_dc 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 Null math operation. Without Null, add a 0.2 Ω error. To elim-
inate noise interference which may be induced by the test leads, a shielded test cable is recommended for resistances 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.
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.
For the total measurement accuracy, add the probe error. The contact strength will significantly influence the measuring
result. Ensure proper contact at the test point you want to measure.
