Test Consideration
In order to make all the test results more creditable, you are suggested to comply with
the following recommendations during testing:
1. Provide proper working voltage for equipments;
2. Ensure a stable test ambient with temperature between 18 °C and 28 °C;
3. Make sure the ambient relative humidity is less than 80%;
4. More than an hour’s warm-up should be done before testing or calibrating;
5. Use copper connector to minimize thermal offset voltage;
6. Use Shielded Twisted Pair with double insulating layer as short as possible to
minimize its resistance and noise.
Because DM3000 Series Digital Multimeter is a type of high accurate measurement
instrument, you must take special care to protect testing procedure against other
disturbs being produced.
