Note:
Accuracy values are stated for an operating
temperature between 64° and 82°F (18° and 28°C). All
accuracy specifications must be derated (increased) by
5.5% for each degree F of operating temperature outside
this range.
For example, an accuracy specification of ±3% between
64°F and 82°F would be derated to:
•
±3.165%
(±3% + (3% x 5.5% x 1))
for operation at
63°F and 83°F
(one degree outside the range)
•
±3.33%
(±3% + (3% x 5.5% x 2))
for operation at
62°F and 84°F
(two degrees outside the range)
•
±3.495%
(±3% + (3% x 5.5% x 3))
for operation at
61°F and 85°F
(three degrees outside the range) · etc.
OPERATING &
MAINTENANCE TIPS
When the
icon appears at the lower left of the LCD,
it’s time to replace the “9V” battery that powers the
meter (although measurements will remain valid for
several hours after the icon first appears). To replace the
battery, follow the instructions on p. 7.
Do not operate the DMM52FSG/DMM53FSG in the
presence of a flammable or explosive gas or near an arc
welder or induction heater.
After subjecting the meter to a large change in ambient
temperature, wait at least 30 minutes before making
measurements to guarantee the accuracy of readings.
Remove the battery when storing the meter or when you
do not expect to use it for an extended period of time
(months rather than weeks).
Do not disassemble the meter or immerse it in water.
