General Inspection

After you get a new DM3000 Digital Multimeter, you are suggested the following steps to inspect the instrument.

1. Inspect the shipping container for damage.

Keep a damaged shipping container or cushioning material until the contents of the shipment have been checked for completeness and the instrument has been checked mechanically and electrically.

2. Check the accessories.

Accessories supplied with the instrument are listed in "Appendix B" in Chapter 6. If the contents are incomplete or damaged, please notify your RIGOL Sales Representative.

3. Inspect the instrument.

In case any mechanical damage or defect, or if the instrument does not operate properly or pass performance tests, notify your RIGOL Sales Representative. If the shipping container is damaged, or the cushioning materials show signs of stress, notify the carrier as well as your RIGOL sales office. Keep the shipping materials for the carrier’s inspection.

RIGOL offices will arrange for reparation or replacement at RIGOL’s option without waiting for claim settlement.

Null Measurement

The DM3000 allows separate null settings to be saved for each of the following measurement functions: dc voltage, ac voltage, dc current, ac current, resistance, frequency/period, and capacitance.

When making null measurements, each reading is different between a stored (selected or measured) null value and the input signal. One possible application is to increase the accuracy of two–wire resistance measurements by nulling the test lead resistance. Null the leads are particularly important prior to making capacitance measurements. The formula used for calculating null measurements is:

Result = reading - null value

The null value is adjustable, and you can set it to any value between 0 and the highest range, for the present function.

Interval time:

You can manually specify a delay between the trigger signal and the first sample that follows. This may be useful in applications where you want to allow the input signal to settle before taking a reading, or for pacing a burst of readings.

• The trigger delay may be set from 400 to 2000 ms.

• The continuity and diode test functions ignore the trigger delay segment.

• If a trigger delay is not manually set, the default trigger delay is automatically set.

• If you manually specify a trigger delay, that delay is used for all measurement

functions (except continuity and diode test).

Reading Hold

The reading hold mode allows you to capture and hold a stable reading on the front panel display. This is useful in situations when you want to take a reading, remove the test probes, and have the reading remain on the display. When a stable reading is detected the reading will hold on the display. Hold scope include 0.01%, 0.1%, 1%, and 10%.

Reading Hold Function

Start the Reading Hold Function, the hold measurement use the following rules judge the reading count:

When Max() - Min() ≤ hold scope x ReadingN, the multimeter hold ReadingN on the display. The display update a new reading was based on the current value of reading and the following three readings before the reading was hold:

Max (ReadingN, ReadingN-1, ReadingN-2, ReadingN-3)

Min (ReadingN, ReadingN-1, ReadingN-2, ReadingN-3)

NOTE

When reading hold started, the input resistance was automatism set to 10MΩ for all DC voltage range. This set-up is conducive to reducing noise arising from the open-loop testing.
