Page 15: Measuring Capability
5. Measuring Capability 5.1 Real-time basic electrical parameters 5.1.1 Voltage SPM33 maximum direct input phase voltage is 400V (ph-N), and line voltage is 500V (ph-ph). Users should be noted this to prevent internal measuring circuit saturation, avoid inaccurate measurements. For high voltage (>500V) measurement, Users need to connect with PT. -
Page 16: Demand Value
5.2.1 Real-time demand Demand value is accumulated value during a specified period divided by the length of that period. SPM33 adopts 2 modes to calculate the demand: Fixed Block and Rolling Block. Users can set demand interval as 5min, 10min, 15min, 30min or 60min. - Page 17 1 or 2 or 3 1 or 2 or 3 or 4 SPM33 provides real-time demand data and peak demand for current (per phase) / active power/ reactive power/ apparent power (per phase and total). User can read the demand from LCD and communication, and can clear demand data to 0.

Page 18: Monthly Peak Demand
Below figure is one example of Rolling Block mode: (Demand intervals is 10 mins, subintervals is 2 mins.) 5.2.2 Forecast demand SPM33 provides data of forecast demand. The data need to be read by RS485 communication. 5.2.3 Monthly peak demand. -
Page 19: Multi-Tariff Energy
Tariff (rate): there are 4 rates, in every period of time, user need to set rate. 5.5 History Energy Data SPM33 record the history active energy data ( total kWh) ： （1） Monthly total kWh in last 12 months. （2） Yearly total kWh in last 10 years. -

Each individual harmonic just can be read by RS485 communication. 5.7 Unbalance parameters SPM33 measures current and voltage negative sequence, positive sequence and zero sequence component, and calculates the voltage unbalance and current unbalance, the formula as below:... -
Page 21: Alarm Setpoint
5.8 Alarm setpoint SPM33 with user definable valued system which can monitor the electrical parameters of the instrument and set the action. When an alarm event occurs, the instrument panel ALARM LED will flash, meanwhile, the display can be switched to the alarm interface to see the type of alarm events, or read the type of alarm through communication, after the elimination of alarm events , ALARM LED will destroy , warning interface will appear as "no."... - Page 22 The lower limit of alarm.

- Page 23 5.8.1 Alarm trigger condition When the setting object meets the trigger condition, and meanwhile it also meets the time requirements, then it will trigger alarm. Throughout the delay time, if the setting object restore within limits, then the alarm setpoint is not activated. If the delay time is 0, it means that once the monitoring object exceeds the limit, it will alarm immediately.
- Page 24 5.8.2 Alarm output When the alarm event occurs, users can check the alarm event from LCD or communication. If the alarm associated one relay, the relay will trigger. Once the alarm disappears, the ALARM LED will be off, and the associated relay will restore.
- Page 25 Bit15 DI 2 switch off For example: On SPM33 LCD, it shows alarm information: C005, then, convert it to binary is “ 1100 0000 0000 0101”, it means there are 4 alarm events: Over-voltage, Over-current, Phase error, DI2 switch off.
