  • Page 23: The Voltmeters

    The Voltmeters Each voltmeter is capable of measuring up to ±100 VDC with 24-bit accuracy. Each voltmeter has its own 24 bit Delta Sigma ADC. The data and power lines for each voltmeter are isolated with a chip-scale air core transformer. This enables each voltmeter to measure different DC voltage sources without any effect on the main board or other voltages.
  • Page 24 Below is a screen shot of the RMS-200 voltmeter overview page. This page shows at a glance all voltmeter readings and provides a gateway for more voltmeter options. In the screen shot below voltmeter 1 is displaying a positive reading of a 12v battery bank.
  • Page 25 Trigger Actions on Boot” check box is used to stop actions from happening when the RMS-200 board is warm or cold started. Each voltmeter has a High, Normal, and Low trigger range. Each High and Low trigger range has a maximum and minimum value. The range in between the maximum and minimum value acts like a dead band area.

  • Page 26: Voltmeter Graphs

    Below is the Low Trigger interface. The Low Trigger is used when the voltage falls below the Low Trigger maximum value. The Normal Trigger is used when the voltage rises above the Low Trigger minimum value. Below is an example of reading the voltmeters on the command line. The voltmeter data files can be found in the /var/rmsdata/ directory.

  • Page 27: How To Measure Amperage By Using A Shunt

    Using a common shunt, it is possible to obtain a millivolt reading that relates to an amperage reading. The voltmeters on the RMS-200 board are perfect for this as they are very sensitive and can easily read millivolt readings. For greater accuracy, put the RMS-200 voltmeters in to low voltage mode by removing the mode jumper for a particular voltmeter.
  • Page 28 Below is an example diagram of how to use RMS-200 with a shunt to measure charging from a solar panel array. The negative solar panel lead is connected to the battery negative terminal. The positive solar panel lead is routed to the positive battery terminal by way of a 50 millivolt 50 amp current shunt.
  • Page 29 This technique can be used to measure DC current being put into your batteries by solar panels, a wind generator, or a battery charger. RMS-200 can monitor your voltage and amperage remotely and alert you to dangerous battery conditions.
  • Page 30 Below is an example of how to use RMS-200 with a shunt to measure current draw from your equipment. The negative load wire is connected to the battery negative terminal. The positive wire is routed to the positive battery terminal by way of a 50 millivolt 25 amp current shunt.

  • Page 31: Need More Voltmeters

    Need More Voltmeters? If the six on board voltmeters on the RMS-200 board are not enough for your needs, you can add six additional isolated voltmeters by adding a USB isolated voltmeter board. The USB Isolated Voltmeter Board gives you control of six +/- 100vdc isolated voltmeters via the standard USB Bus.
  • Page 32 Clicking on the VDB icon in the left navigation bar takes you to the main setup page of the USB Isolated Voltmeter board. Below is a screen shot of the familiar voltmeter setup page. This page shows at a glance all voltmeter readings and provides a gateway for more voltmeter options.
  • Page 33 DVM. The “Suppress Trigger Actions on Boot” check box is used to stop actions from happening when the RMS-200 board is warm or cold started. Each voltmeter has a High, Normal, and Low trigger range. Each High and Low trigger range has a maximum and minimum value.
  • Page 34 Below is the Low Trigger interface. The Low Trigger is used when the voltage falls below the Low Trigger maximum value. The Normal Trigger is used when the voltage rises above the Low Trigger minimum value.

  • Page 35: The Temperature

    The RMS-200 web interface has High and Low triggers that can be set to fire alerts or scripts when the temperature is either too high or too low. Use the relay scripts to turn on a cooling fan for example.
  • Page 36 Below is the Low Trigger interface. The Low Trigger is used when the temperature falls below the Low Trigger value. The Normal Trigger is used when the temperature raises above the Low Trigger value. Below is an example of reading the temperature on the command line. Note: the file tempf contains the board temperature in Fahrenheit.
