SCALE MENU
The
Scale Menu
allows the operator to tare, verify, and
calibrate the oven’s integrated scale.
NOTE
The operator can also tare the integrated scale by
pressing the
(
TARE
)
key when the default screen is
displayed.
The scale should only be verified or calibrated when the oven
chamber is at room temperature. When calibrated correctly, the
scale complies with the following standards:
♦ AASHTO M 231, Standard Specification for Weighing
Devices Used in the Testing of Materials
♦
ASTM D 4753, Standard Specification for Evaluating,
Selecting, and Specifying Balances and Scales for use
in Soil, Rock, and Construction Materials Testing.
Please refer to these standards when identifying the accuracy
and linearity requirements. Troxler recommends calibrating the
scale should it fail the
Verify
test.
