4. Installation
The operation method is explained by this description under the conditions installed and connected propery.)
5. Operating features36. Initial setting
It is required to perform an initial configuration, before using it. The flow of setting operation is explained below.
6.1 The state at the time of factory shipments
The equipment has no power-on switch.
When voltage is applied to the power supply terminal, the equipment begins to measure.
When operating for the first time, this meter begins operation with the setting value at the time of factory shipments. When eachparameter is specified at the time of order, there is no necessity for the following setting operation. Since this meter starts
operation by the demanded specification, please confirm it. Please perform the following operation to change a setup anew.
In addition, when you use except the specification at the time of an order, please set up by the first setup of 17 items.
6.2 Initial setup●Procedure of an ini al setup(1) Please setup only a necessary item. During setting operation in each setup item, when key operation is not performed morethan for 3 minutes, operation becomes invalid and returns at the state before operation.
(2) The setup will be determined, if the key of "SET" is pressed while setting up each item. And it returns to a setting menu.
Moreover, when it returns to a setting menu by the "W/V/A" key, the setup till then disappears.
(3) Please press the "W/V/A" key to return from a setup state to measurement mode.
