In particular, with its long service life, this meter is not only widely used in electrical panels but also used to display other electrical data such as voltage and current coefficients in many buildings. Today, we will go into detail on how to install the Autonics MX4W-V-F1 electric meter, ensuring you can take full advantage of the superior features of this device for every application.1. Overview of Autonics MX4W-V-F1 (MX4W series) electric meter
The MX4W-V-F1 (MX4W series) power meter has an LCD display with large, easy-to-read white characters. The W96 x H48 mm MX4W series has a large display that can display various alphanumeric characters. The series has a variety of output options to suit different installation requirements. The power and input terminals are designed to be isolated from each other, so that one power supply can power multiple devices. In addition, the MX4W series has many other options including a power factor display function to display the analog output from the power factor converter. The compact rear size of 20 mm allows users to install in tight spaces.

High voltage level warning
• Press 4 seconds to enter group 2 parameters select
(set output 1 alarm operation)
• The settings are 
• Press to save, then press within 3 seconds to exit to main screen
• Press to enter group 0 parameter, high limit 
set to 26Low voltage warning
• Press 4 seconds to enter group 2 parameters select (set output 1 alarm operation)
• The settings are 
• Press to save, then press within 3 seconds to exit to main screen
• Press To enter group 0 parameter, set low limit to 20High/Low Voltage Level Warning
• Press 4 seconds to enter group 2 parameters select (set output 1 alarm operation)
• The settings are 
• Press to save, then press within 3 seconds to exit to main screen
• Press to enter group 0 parameter, high limit set to 27
• Press To bypass the low limit, set to 20Set the zero adjustment level
Force the display value of the measured input to 0 (zero).
● Zero adjustment range: -99 to 99
● Zero adjustment method:
Method 1 : Hold 
for about 3 seconds
Method 2: Set the display hold level/zero adjustment level [DI-T] of parameter group 2 as the zero adjustment level [ZERO]. Press the push button connecting pins 3 and 4 and adjust the zero level.
※When the zero adjustment is completed by method ① or ②, the display will show the zero level and the adjustment value will be automatically saved at [ZERO] of parameter group 1.
If the zero adjustment range is exceeded, the [OVER] error will flash twice and it will return to RUN mode by maintaining the previous setting value.Set reset mode
