3.3 Precautions Related to a Specimen
Static Electricity
• Synthetic resin- and glass-made specimens are easily charged electrically
• Weighing electrically charged specimens makes the displayed value unstable, reducing the reproducibility of a test result
• Neutralize electrically charged specimens before measurement
Magnetism
• Specimens affected by magnetism weigh differently depending on the position on the pan, reducing reproducibility
• Eliminate the magnetism or place the specimens on a container/plate to protect the weighing mechanism
Moisture Absorption/Evaporation
• Wet or volatile specimens can cause the displayed value to continuously fluctuate due to evaporation
• Put these specimens in a container with a tight fitting lid to prevent evaporation during the weighing process
Specimen Temperature
• Difference in temperature between specimens and the windshield interior generates convection flow, causing errors
• If specimen temperature is excessively high or low, allow its temperature to stabilize at room temperature prior to measuring
• Ensure the windshield interior temperature is equal to room temperature prior to measuring
• Body temperature of operator affects measurement results; handle specimens with tweezers and refrain from putting
hands in the windshield during operation
3.4 Display Navigation
Use the F-keys to navigate through the menus and enter numerical values.
