Panel Meters are typically used to measure a wide range of electrical and electronic parameters. One common type of panel meter is the Hour Meter, which is used to measure the amount of time a machine or device has been used. The panel meter can be fitted with a mechanical or digital display and be connected to a variety of sensors and processors that are capable of accurately measuring current and voltage, frequency, power, and other parameters.

The LH2H-F-HMS-FV-N Panel Meter is part of a range of Hour Meters designed to measure the running time of motors, pumps, or other devices. It features an easy to read display with a 6-digit counter and two-level backlighting, and is designed to meet international safety standards. It can be programmed to measure in hours only or hours and tenths of an hour, as well as the ability to view time in HHMMSS (hour-minute-second) or HHMM (hour-minute) formats.

The panel meter has four external connections, labelled F, L, H, and N. The F connection is the main power supply for the panel meter, which must be between 10 to 50 VDC or 10 to 30 VAC. The L connection is the alarm output, which is triggered when the measured time exceeds the preset value. This output can be programmed to trigger an alarm buzzer, LED, or relay depending on the application.

The H connection is used to connect to the motor or device that is being monitored. The panel meter can be programmed to detect the start or stop of the motor or device, and then count up or down based on the change in state detected.

The N connection is used to connect to an external input. This allows the user to manually reset the counter, or to feed it an external clock signal, allowing for subtractive or additive counts.

Overall, the LH2H-F-HMS-FV-N Panel Meter is an economical and high-performance solution for measuring the running time of motors, pumps, and other machines. With its easy-to-read display and programming options, it provides users with an accurate and reliable measure of current operation times as well as an alarm output for alerting users when the operation time has exceeded a certain threshold.
