The CVM-1D is an instrument that measures, calculates and displays the main electrical parameters in industrial and domestic single-phase power networks. The measurement is an RMS value made by direct measurement of the current and voltage. The measured and calculated parameters are shown in the table of variables.

1.- Button

The CVM-1D analyzer's front panel has a six digit LCD display as well as a button function that enables the user to navigate through the different display screens of the primary electrical variables.

This button is used for two types of navigation, depending on how it is pressed:

SHORT PRESS: This type of press occurs when the user maintains the function button pressed for less than two seconds. With a short press, the device moves through the different navigation screens, displaying all the electrical parameters on the display (refer to section 2.- Display). In numerical setting, the short press allows a cyclical increase the value of the digit.

LONG PRESS: This type of press occurs when the user maintains the function button pressed for longer than two seconds. With a long press, the device intermittently displays the maximum and minimum values of the variable that is displayed at that moment. With a long press on the partial power values, the unit resets these values. In numerical settings, long press allows the left lateral selection and posterior digit validation. If the selected value is not correct, the digits will blink indicating the user to enter a correct value (refer to section 5.- Setup, allowed values).

2.- Display

The unit's front panel incorporates an LCD display with six digits. By repeatedly pressing the function button located on the front panel, the unit displays the different measured electrical parameters and the symbol corresponding to the displayed variable.

3.- Measurement
