Chapter 2 Performance Verification Test
This chapter introduces the routine test methods of DM3058/DM3058E performance
verification test and the quick test methods are also contained.
Zero Offset Verification
The zero offset verification inspects the zero offset performance of the multimeter. It
is necessary only when a regular offset occurs to a function and range.
The zero offset verification procedures are as follows.
1. Make sure you have carefully read the "Test Conditions".
2. Use a 4-terminal short-circuiter to short-circuit the Input HI-LO and Sense HI-LO
terminals and open the current input terminal, as shown in Figure 2-1.
3. Test the functions under different ranges specified in Table 2-1 one by one. Set
the reading rate to "Slow" and turn off all the math operations.
4. Compare the test results with the test limits in the table.
