Fig.1-2 is the rated voltage of 125 V. It is provided with the product which is 100 V system line voltage.When you use the DME1500 which you have changed the line voltage range to 200 V system, replace with an appro- priate power code.
DME1500 results in malfunction or the production of large noises from the DME1500. To ensure safety, provide secure grounding. The DME1500 can be grounded by the method specified below. Plug the AC power cord into a 3-pole power outlet upon which grounding construction has been performed.
2.1.2 Over-range indication An input is over-range if it exceeds the full scale of the selected range. DME1500 indicates an input is over-range by lighting the “—OL—” pattern on display. 2.1.3 Input overload protection The maximum allowable input is shown as table 2-1. Please pro- ceed the measurement accordingly.
Connect the test lead to the measuring points and read the displayed value. NOTE • After measuring high voltage to 1000V dc, errors may occur when the 100µV is measured. Allow up to one minute prior to making low-level measurements. E-18 MEASUREMENT TUTORIAL DME1500...
