TABLE 1: Three Power Measurement Display Modes
7.2.1 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
7.3 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.
7.4 Storing and Clearing Accumulated Measurement Data
The meter memorizes accumulated reading data when the POWER position of the
Rotary Switch has been changed to another function after Power measurements
have been made (this activates the memory utility). To recall accumulated data, re-
select POWER on the Rotary Switch, the meter displays stored data in EEPROM.
To clear accumulated readings: Set the Cost per KW/H to 0000.0 in mode 2 (left
sub-LCD display).
7.5 General Power Measurement Notes:
1. When POWER is selected via the Rotary Switch, automatic power-down
works only when the watt measurement reading is zero.
2. When POWER is selected on the Rotary Switch, the FUNCTION key will not
operate when pressed.
3. To save (store) the cost per hour, KW/H, and accumulated cost data, press
the FUNCTION key or turn the Rotary Switch to another range AFTER
DISCONNECTING THE POWER ADAPTOR. Never change the Rotary
