(2)
Always use the unit within the specified voltage range: otherwise, it may cause a fire,
electric shock or personal/equipment damage.
(3) For the purpose of functional improvement, the information written herein may be
changed
without prior notice.
(4) Information contained herein is considered accurate to the best of our knowledge.
If you have any question or comment on the information, please contact us or our
distributor.
(5)
Read this manual carefully and thoroughly before starting to operate the unit,
and keep the manual available for future reference.
1. Before Using the Unit
Thank you for purchasing our A9000 Series Digital Panelmeter. Please
make sure that the operator who uses the panelmeter keeps the manual
on hand. Also, the meter should be checked upon receipt for damage
that might have occurred while in transit. Should the product be
damaged or any accessory be missing, notify your sales representative
or our sales office directly.
1.1. Model and Suffix Code Configuration
The model and suffix code of the A9000 series are as shown below.
Check that the product received matches the one you selected when
ordering.
1.2.
Checking the Accessories
The A9000 series accessories include one copy of this instruction
manual, one unit label and a connector
for BCD outputs / external
control inputs.

2.3 How to Mount the Unit on the Panel
(1) Do not install the unit where it is exposed to dust, particles, chemicals harmful to
electric components, corrosive gases, etc.
(2) When this unit is installed inside other equipment, pay attention to the heat radiation
and keep the heat inside the equipment 50°C or below.
(3) Exercise care so that the product is not subject to vibrations or shocks.

Terminals and Connections
①：
Input terminal HI (+ input terminal of 11 or 12, 22 or 23 -range )
②：
Input terminal HI (+ input terminal of 13 or 14, 24 or 25 -range )
③：
Input terminal LO (- input terminal )
* Selecting input range can not be done only by connecting input signal
to a suitable terminal. Please set the RANG parameter in condition data.
See
“4.6.(8) Setting condition data”.
* Make input signal wires as short as possible and keep them away from
other signal wires.
* Use two-core shielded cables in locations with a lot of external noise
and connect the external sheaths to the LO side of the signal source at
one point.
* If harmonic noise is superimposed on an input signal, insert a low-pass
filter in the input. However, care must be exercised depending on the
usage conditions because a delay in response time is caused in time
constant.
④⑤⑥：
NC terminals
*Do not connect anything to the NC terminals.
⑦：
Power terminal (In case of DC POWER : 0 V)
⑧：
Power terminal (In case of DC POWER : +V)
*This panelmeter has no power switch. Connecting it to a power source
causes it to be operable immediately.
