WATANABE ELECTRIC INDUSTRY AP-301 Series Instruction Manual

DIGITAL PANEL METER
MODEL AP-301 Series
INSTRUCTION MANUAL
(1) The application of voltage or current exceeding its maximum
allowable value to the input terminals may result in instrument
damage.
(2) The supply of power out of its allowable range may cause fire,
electric shock or instrument failure.
(3) The content of this manual may subject to change without prior
notice for product improvement.
(4)The manual is carefully prepared. However, if any question arises,
or any mistake, omission or suggestion is found in the content
of this manual, contact your nearest our sales agent.
(5) After read this manual, please keep it as anytime can see.
１.OUTLINE
The AP-301 Series digital panel meter is thin and light meter uses
only 3-1/2 digits. The meter uses a 5V power supply driving and
has large LED(Light Emitting Diode)numeric display elements
(Heght:14.2mm)which are easy to see in spite of the small case.
The display has holding and blanking functions and can show a
maximum value of 1999. The circuit largely consists of an
independently developed LSI, which is more reliable than hybrid
integrated circuit.
1 to 5V input, boards for external set screws, a terminal for a
mother board fixture, a power source isolation board and other
options can be provided as required by the customer.
