Elenco 3 1/2 Digit with Temperature - Manual (Page 12)

• When you change the measurement function, the meter will
regard its auto range as current range.
• In the auto range mode, the “AUTO” symbol will appear on
display and the manual range disappears.
3. Enter or exit manual range mode
• Press the RANGE button to select the manual range mode
and the “AUTO” symbol disappears. Each press of the
RANGE button increases the range. When the maximum
range is reached, the meter restarts at the lowest range.
• Press and hold the RANGE button for more than two
seconds to return to the autorange mode and the “AUTO”
symbol will appear on the display.
7. Making Measurements
Preparation
Checking the Battery Voltage
Rotate the Function Rotary Switch to any position away from the
OFF position. The battery voltage is adequate when the indication
is clear and the symbol is not on the display.
If the symbol appears on the display, or nothing shows on the
display at all, follow the battery replacement procedure shown in
related items in this manual and replace with new batteries specified.
Measuring Voltage
Voltage is the difference in electrical potential between two points.
The polarity of AC (alternating current) voltage varies over time, while
the polarity of DC (direct current) voltage is constant.
Danger
To avoid the danger of electric shock, never make measurements
on a circuit over 600V AC/DC (electrical potential to ground 300V
DC/AC). Do not operate the Function Rotary Switch during
measurement. Do not make a measurement when opening the
battery cover and the meter case.
