2-3 Turning the Meter ON
To turn the meter on, press the
Power
button to “IN” position located on the
lower right of the front panel. When the meter is turned on, the primary and
secondary displays light for about 2 seconds while an internal self-test
running by its digital circuitry. If the
Hold
button is pressed while the
power-up sequence is in progress, all segments and annunciators of the entire
display remain on until another button is pressed. Then the power-up
sequence continues.
After the meter completing its power-up sequence, it resumes the power-up
measurement configuration stored in non-volatile memory. The power-up
default configuration status set at factory is shown in Table 3-2.
2-4 Selecting Current Input Terminals and Measurement Range
If current (dc or ac) is being measured in the Auto-ranging mode, with a
signal input on the 500mA terminal, the meter will select the range
500
µ
A~500mA automatically.
If a signal input is applied to the 10A input terminal, the meter will select the
5A or 10A range automatically.
