temperature of its parts whether in a normal or abnormal (failure) state when used in an explosive gas
atmosphere.
This document explains the operation and notes on the use of the AZ Series intrinsically safe explosion-proof
electronic balance.
Carefully read this document before using the balance in order to use it efficiently. After reading this document,
please keep it at hand for future reference.

1-2Instructions for Proper Installation
Avoid installing the balance in the following places. Installing the balance in such places may result in
inaccurate measurements.
•Places where the temperature is low or high, or the humidity is high
•Places where the balance will be subjected to direct sunlight
•Places where there is much vibration(including places where the floor or base is unstable)
•Places where the balance will be directly exposed to wind, cool air, or heated air (places where the
balance will be directly exposed to cool air from air conditioners or refrigerators, heated air from air
conditioners or heaters, or wind from fans, etc.)
•Places where there is excessive dust
•Places where there are high levels of noise
•When carrying the balance, hold the lower parts of the pole base and weighing section to lift the
balance. Holding other parts such as the pole to carry the balance may damage the balance.
•After installing the balance, leave it for a while at room temperature before using it.
