Page 8: Setting The Instrument Type
MI 2130 VoltScanner Setting Up the VoltScanner 2.3.2 Setting the Instrument Type Before sending the Settings parameters to instrument for the first time you should select Instrument type. Go to Config menu and choose Instrument type option. The following Instrument Settings window will open: 2.3.3 Setting the Thresholds Click the Settings button in the toolbar in the main window, or go to the File menu and choose Settings. - Page 9 MI 2130 VoltScanner Setting Up the VoltScanner VoltScanner can operate in two modes - Event & Transient and Periodics. Select the appropriate menu for the VoltScanner to operate. Event and Transient mode In this mode the VoltScanner records single events that fall above or below the set thresholds.
- Page 10 MI 2130 VoltScanner Setting Up the VoltScanner Voltage Swell A voltage swell is an increase in line voltage that can last for an indefinite period. The VoltScanner records swells that are above the set threshold for at least one cycle (20ms/50Hz) with a 3 volts hysteresis.
- Page 11 MI 2130 VoltScanner Setting Up the VoltScanner Voltage Transient A voltage transient is a short duration overvoltage which lasts a few milliseconds or less. The VoltScanner records transients both on L-N and N-PE inputs, which are above the set threshold and last at least 1us. It records magnitude and phase of a transient.
- Page 12 MI 2130 VoltScanner Setting Up the VoltScanner below the set threshold for at least three cycles. The following picture shows a short frequency variation (high frequency), lasting only two cycles. Frequency Variation Voltage Interruptions Voltage Interruptions can be the result of power system faults, equipment failures and control malfunctions.

Page 13: Sending The Parameters
MI 2130 VoltScanner Setting Up the VoltScanner Voltage In this section, the nominal value (220 - 240V or 110 - 130V) of the supply voltage must be set. Memory In this section, you can choose between two modes of storing data. VoltScanner can stop recording when memory is full, or can operate as circular FIFO (first in first out) register and overwrite the oldest data. - Page 14 MI 2130 VoltScanner Setting Up the VoltScanner If you want to proceed click the yes button. A notice Connecting to Instrument will appear until the communication is over, which may take up to 8 seconds. If everything is OK, the following dialog box will appear: Click the OK button to clear the message.

MI 2130 VoltScanner Plugging in the VoltScanner 3 Plugging in the VoltScanner After the parameters were successfully sent, the VoltScanner is ready to begin recording. Every 8 seconds it checks the line voltage. If the voltage is higher than 70V, it wakes up from this power down mode and starts recording. - Page 16 MI 2130 VoltScanner Plugging in the VoltScanner Note: Before using the VoltScanner for the first time, plug it in an outlet for at least 5 hours or over night, so that batteries will charge up. If the VoltScanner hasn’t been used for more than two months, also plug it in an outlet for at least 5 hours or over night before using it again.

Page 25: Supply Voltage Interruptions
MI 2130 VoltScanner Downloading and Analysing Data EN 50160 Graph This bar graph represents the results of EN 50160 analysis. First bar represents the number of swells and dips, second bar the number of interruptions and third bar the percentage of frequency values outside ±1% of nominal frequency. The limit line for first two bars represents 100 events and for the frequency bar it represents 0.5%. - Page 26 MI 2130 VoltScanner Downloading and Analysing Data In the Event & Transient mode an interruption is represented as one event with the following data (as shown in the next picture): the beginning time, duration, magnitude (which is zero) and event type (which is interruption).
