Instruction manual

---------------Once each for the converter and detector

„Inspect the flowmeter for indications of damage that may have occurred during shipment.

„Make sure the type and specifications of the flowmeter are in accordance with the ordered specifications.

If you cannot find the items listed above or any problem exists, contact your nearest Toshiba representative.

1.2 Strage

To store the electromagnetic flowmeter after opening the package, select a storing place as follows and keep it under the conditions described below:

1.1 Product Inspection CAUTION

(1)Avoid places where there is direct sunlight, rain or wind.

(2)Store the product in a well-ventilated place. Avoid places of extremely high humidity or extremely high or low temperature. The following environment is recommended:

Humidity range: 10 to 90% RH (no condensation)

Storage temperature: –25 to +65° C
(3)Avoid places where vibrations or mechanical shock occur.

(4)If the cover of the converter is left open while being stored, gradual deterioration of circuit isolation can be caused. Therefore don’t open the cover until it is connected with wires.

(5)To put the flowmeter temporarily on the floor, place it carefully with something, such as block orstopper, to support it so that the flowmeter will not topple over.
