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.
This technology enables the ability to measure (but not limited to):
•
positive and negative voltages
•
separate power sources
•
individual batteries in a battery bank
•
shunt voltages for equipment that may be drawing or generating power.
•
solar panel voltage and amperage
•
wind turbine voltage and amperage
•
battery charger voltage and amperage
Each voltmeter has a Mode Jumper that when removed puts the voltmeter into low
voltage mode. In this mode, the volmeter has a range of ± 2.0 VDC and has over 4 million
steps. This is perfect for calculating amperage by measuring voltage drop across a
current
shunt.
Note 1:
Voltmeters that have nothing hooked up to them so that the positive and negative
inputs are floating may read spurious positive and negative voltage readings, this is
normal. You may dampen the voltage reading by sacrificing accuracy using the precision
box. Use a number between 2 and 6 to increase or decrease the decimal place.
Note 2:
Due to variations in components and the manufacturing process, voltmeter
readings may differ slightly from each other and from your hand held DVM. Use the
adjustment box to fine tune the voltmeter to display the expected value.
