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
4.2.1「M」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. and average values depending on the display
parameters.
 Max./Min. Voltage(L-L，L-N，Average)
 Max./Min. Current(Per phase，Average)
 Max./Min. Voltage & Current unbalance rate
 Max./Min. kW(Per phase，Total)
 Max./Min. kvar (Per phase，Tota l)
 Max./Min. kVA (Per phase
，Total)
 Max./Min. kW-t, kVA-t, kvar-t
 Min. PF
 Max./Min. Frequency
 Max. Power Demand
4.2.2 「P」Button
「P」Button is for displaying power selection. Press「P」Button successively to obtain:
 Active power (P) per phase and total
 Reactive power (Q) per phase and total
 Apparent power (S) per phase and total
 Total active power (P), reactive power (Q) , apparent power (S) and power factor(PF)
 Total active power (P), reactive power (Q) , apparent power (S) and frequency(F)
 Previous power demand kW, , demand subinterval remain time (sec) and current power demand
kW
4.2.3「E/T」Button
「E/T」Button is for displaying Energy & Time. Press「E/T」successively to obtain the following values
in the zone 8 (bottom lane of the screen)
 Total active energy (kWh-t)
 Total reactive energy (kvarh-t)
 Total apprerant energy (kVAh-t)
 Total meter running hours (Total)
 Total meter running hours with load (Net)
 Year-Month-Day
 Hr-Min-Sec.
4.2.4 「V/A」button
「V/A」button is for displaying Voltage and Current. Press button successively to obtain
 Phase to phase voltages and average (U)
 Phase to neutral voltages and average (U)
 Instantaneous current (I)

Unbalance rate for voltages and current
 Voltage eligibility rate
 THD(V、I)
「V/A」button then「M」button
「P」button then「M」button
