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 1200mA terminal (5492) or 120mA terminal (5491), the meter will
select the range automatically.
If a signal input is applied to the 12A input terminal, the meter will not select the
range to 12A automatically. User will need to select the current measurement
range to 12A manually.
2-5 Using the Pushbuttons
The meter functions and operations can be selected by pressing the pushbuttons
on the front panel select.
A summary of pushbuttons is shown in Figure 2-4.
Pushbuttons can be used in three ways. User can:
! Press a single button to select a function or operation.
EXAMPLE:
(Press) to select AC volts for the primary display.
! Press a combination of buttons, one after the other.
EXAMPLE:
to select AC volts for the primary display, and then
to select the frequency measurement.
