5 Meter Function

5.1 Energy measurement

HXE34 Keypad meter can measure energy in security mode, which means it

records reverse energy as forward one, and adds this value to total energy

consumption. The registration range is 000000.00 ~ 999999.99 kWh.

|A| = |-A| + |+A|

The meter can also measure instantaneous power, voltage and current.

5.2 Communication

HXE34 keypad meter has optical port on the top right corner; the optical port is

designed in accordance with IEC62056-21.Meter parameters are programmable

through Hexing PC software.

5.3 STS function

5.3.1 Purchase a token

Similar to a pay-as-you-go mobile phone, credit can be purchased from any

authorized vending station.

The user will supply the vendor with meter serial No. and the amount that he/she

wishes to purchase. If meter serial No. is not available, it is still possible to

purchase electricity supplying with other registered information such as physical


13/26


13

address of the user.

The vendor will in return hand the user with a token with a 20-digit credit code,

which is generated using STS encryption techniques and protocol. All data such

as monetary amount, meter key. and date of transaction reside in this code. In this

way, all tokens are meter serial number specific, which means that a token can

only be used on one specific meter.

If user buys token from a vendor and would for some reason lose it, no one would

be able to use the token (on a different meter) unless it is entered into the initial

buyers meter. This makes a very safe and controlled environment.

5.3.2 Credit the meter

The procedure of the credit meter is as below:

1. User get credit TOKEN, such as 64188786299167809510 after

purchase credit at CDU or POS. This TOKEN is encrypted by credit value,

data and key.

2.Please key in 20-digit code that appears on the token through keypad on the

meter.

The code will be scroll display on the LCD from right to left. Every 4 digits will

be separated by -.

During the process of topping up stored value, the time interval allowed for

keying between the 2 digits should not be more than 10 seconds. Otherwise the

digits, which have already been keyed, will be deleted automatically.

The following three LCD images display the process of entering credit code
