2. PRECAUTIONS
The AD-4532B is a precision instrument. To get the most from your AD-4532B, observe the following
precautions.
2-1 Unpacking
Unpack the AD-4532B carefully and confirm that everything is contained. Keep the packing material
if you want to transport the indicator again in the future.
2-2 Precautions Before Use
Avoid water and moisture.
Avoid vibration, shock, extremely high temperature and humidity, direct sunlight, dust, and air
containing salt or sulfurous gases.
Avoid places where inflammable gases or vapors are present.
The operating temperature is -5°C to +40°C.
The power requirement is 85 VAC to 250 VAC. Use a stable power supply free from
instantaneous dropout or noise. Avoid sharing with the power line.
Connect a grounding wire to the ground terminal. Do not share grounding with other units that
create electrical noise.
Keep cables sensitive to electrical noise away from power cables and other sources of
electrical noise.
Connect a non-inductive load of 5 kΩ or more to the analog output terminals.
Use 6-wire shielded cables to connect sensors. If 4-wire cables are used, connecting long
cables to the sensors will increase the total cable resistance and cause measurement errors.
Keep these cables away from power cables and other electrically noisy cables
Do not connect the AD-4532B to the power supply before installation is completed. The
AD-4532B has no switch to disconnect the power supply.
Use shielded input/output cables. Connect the cable shield to the FG terminal or the indicator
housing.
