4.2 Operation
The SPM-3 is equipped with four function buttons to easily navigate through all values and to modify
device settings. From left to right, there are
「
M
」
、「
P
」
、「
E/T
」
and
「
V/A
」
respectively.
Button
「
M
」
displays maximum and minimum values
Button
「
P
」
displays power for each phase, total power, power factor (PF), frequency (F) and power
demand.
Button
「
E/T
」
displays energy
、
RTC
Button
「
V/A
」
displays voltage, current, unbalance rate, eligibility rate, and THD

Button
Press successively to present the maximum, minimum and average values of present measuring
parameters. For example, if SPM-3 is currently displaying “Voltage” with “U” shown on the left of the
screen, pressing “M” Button will show the
Max./Min.
and average values of Voltages. The following is the
list of all the values that can be shown for
Max./Min.
