⚫ Make sure you are in the settings mode. To get to this mode follow the procedure above for
ensuring the meter has the correct settings to read accurately.
► Once in the “Setting” mode, press the “SET” to get to the “S-04 PULSE” page. This config -
uration is to enable the meter to output pulses based on the Active Energy(P) or the Reactive
Energy(q).
▪ Press “SET” to modify the setting; the cursor should now flash.
▪ Press “SCROLL” to select the type of energy to output.
▪ Press “SET” to confirm the selection.
► Press “SCROLL” to get to the “S-13 Pn” page. This configuration will represent the num -
ber of pulses the meter will output per kWh/kVarh. This will be based on the required speci-
fication.
▪ Press “SET” to modify; the first digit will begin to flash
▪ Press “SET” to move to the next flashing digit.
▪ Press “SCROLL” to change the flashing digit’s number.
▪ Press “SET” on the last digit to confirm all the changes after they have been made.
The procedure to calculate what value to enter in the meter for the DO Pulse constant is as fol-
lowed:
First determine how many pulses are needed to represent 1 KWh or how many KWh will repre-
sent 1 pulse. The former is focused on smaller consumption.
In this procedure, we will assume 1 pulse = 10kWh is what is needed. Then follow these steps:
➀ Multiply the PT ratio and CT ratio i.e. PT1/PT2 * CT1/CT2
Example: PT ratio: 6600V/120V, CT ratio: 2000:5A => 6600/120 * 2000/5 = 22,000
NOTE: If no PTs were used, enter the PT ratio as the default on the meter, i.e. 400/400.
If the CT2: 80/100/200mA, consider this as 1A for the calculation
➁ Divide 10KWh by 22,000 i.e. (10/22000) kWh = (1/2200) kWh
➂ This means 1 pulse = (1/2200) kWh; therefore 2200 pulses = 1 kWh
➃ Since we get 2200 pulse/kWh, enter 2200 as the pulse constant into the meter
► Press “SCROLL” to get to the “S-14 PH” page. This configuration will represent the pulse
