Three Modes of Power Measurement Displays
There are three modes of Power Measurement Displays. These modes have
different Main LCD and Sub-LCD displays related to power. Mode 0 is the initial
mode that the meter will be in when the POWER position is selected with the
Rotary Switch. A zero will display to the upper left of the left-most sub-LCD
indicating Mode 0. Use the UP and DOWN arrow keys to scroll through modes 0
through 2. The digit to the upper left of the left-most sub-LCD indicates the present
mode. Refer to the Table below for an overview of the display modes for the Main
LCD and the three Sub-LCDs. Then refer to the explanations below for
accumulated watts, cost, etc.

TABLE 1: Three Power Measurement Display Modes
Explanation of terms in TABLE 1
• Watts: True Power reading of load/appliance measurement
• AC Load Current: Current measurement for load/appliance under test
• AC Voltage: Voltage measurement of load/appliance under test
• Phase angle: Phase difference (from –90 to +90 degrees) between input
source and load
• EDIT the Rate Cost per hour in $: This is where the user programs the Cost
per hour (instructions on how to set this value are given in Section: 7.3)
• Accumulated Consumption Cost in $: This is the total cost of consumption
monitored since measurement session began (displayed in US$)
• Accumulated Watts: Wattage accumulated from when measurement session
began up to the present (displayed in KW/H).
• KW/H: Kilowatt hours
• Unit 1 KH/H: Reference value of 1KW/H
Programming Cost per Hour
1. Go to mode 2 using the UP/DOWN keys to scroll through the modes. The mode
designator is the digit to the upper left of the left-most sub-LCD.
2. The left-most sub-LCD is where the Cost per Hour is programmed.
3. Press the SET/RESET key to begin editing the left most digit will flash. Enter the
desired value via the UP/DOWN keys. While programming, to move to the next
digit for editing, use the SET/RESET key. Digits are selected and ready for
editing when they are flashing.
4. Press the SET/RESET key until the digits cease flashing when finished editing
the cost per hour value and then measure power in the desired mode
Note: Based on the consumption cost per hour programmed, the meter displays
the expected rate cost per hour automatically. Currency is displayed in US dollars.
