Power Monitoring Display
The voltage reading is displayed when power is first turned on and will
remain until the Function button is pressed. The FUNCTION button is the top
button next to the display. Pressing this button will cycle through the eight
meter functions. The order of the functions is as follows: Voltage, Amperage,
Watts, VA (apparent power), Hz (frequency), PF (power factor), Kwh (kilo-
watt-hour), Time (clock).
The SET button is the bottom button next to the display.
The Kwh and clock function can be reset by turning the power switch off for
3 seconds.
To set a load current alert hold the SET button for 3 seconds, then press
the FUNCTION button to start stepping up the current in 1 amp increments.
Once the desired amperage is reached press the SET button to save. The
display will then flash if the load current limit is exceeded.
Over Voltage will be indicated on the display by “OUP” and will occur when
the input voltage is above 145 volts.
Over Current will be indicated by a blinking screen when the input current
exceeds the selected amperage level.
