2.2.2 Large LED Display DU-330 Series tester uses a large LCD display. With it’s well display format design, it can display all setting parameters, test results, step numbers, memory numbers etc. simultaneously in one display area. This allows the operator to see in the most convenient way all necessary testing parameters under setting mode, and test results. - Page 11 2.2.4 Saving and Recall Setting Parameter DU-330 Series has internal memory for storage of setting parameters. It provides 9 groups of memories and each group has 99 steps of setting parameters. Any of these 9 groups and 99 steps of memory can be recalled for usage or change of parameters. This feature can save time and effort to set testing parameters whenever is required.

5. Operation Instruction 5.1 CAUTIONS - BEFORE OPERATION 1. Make sure the AC power line supply matching the selected voltage range before turning on the AC power switch. 2. The tester has self-calibration function which performs right after the power switch is “ON” Should there be any extra-ordinary situation happened turn off the in power switch and un- plug the AC power source. - Page 18 2. Test Mode Set Up: AC / DC / IR Test mode can be assigned by pressing ∆ or ∇. Setting can be confirmed by pressing [ENTER] and the cursor automatically jumps to next setting parameter. 3. Leakage Current Hi Limit: 0.10 ∼ 15.00 mA (DC 7.50mA) Value of current can be set by pressing the ∆...
- Page 19 If test mode has been selected as IR, the cursor is highlighted at the position of the value of Insulation Resistance for High Limit. Press the ∆ or ∇ key to change the value and confirmed by pressing [ENTER], thus position of the cursor will jump to next page.
- Page 20 7. Test Time Setting: 0.00 ∼ 99.9 Sec. or 0.00 Sec. for continuous test “Test Time” is high-lighted by the reverse video cursor. The assigned length of test time can be changed by pressing the ∆ or ∇ key. If 0.00 Sec.is set, the test will perform continuously until [RESET] is key in.
