This sealed High Voltage Adapter allows the Xantrex XBM series E-meter to work with battery pack voltages greater than 50V and less than 350V. This low cost solution provides accurate voltage scaling, with noise filtering for the E- meter.
To configure the E meter for higher voltages, use the Set function and select the F16 setting and select 1-10 sacle. (See E-meter manual).
The voltage on the E meter display will be decimal shifted and internally scaled to read the battery voltage correctly. Other E meter settings may require adjustment, like battery full voltage and alarm settings (if applicable).

Self Adhesive tape on the protective case allows simple mounting. Clean off a 1" x 1" flat area that will serve as a mount, then peel and stick the case to the cleaned surface.
Simple Installation is as follows:
The 18 gauge heavy wire goes to the Battery Pack (Orange to battery +. Black to battery -).
The 22 gauge thin wire goes to the E-meter (Red + to Vs Input of XBM. Black - to - Input of XBM).
Standard wire length is 34" for the Battery pack, 34" for the E meter) Optional lengths available at the time of order.
Twisted pair is recommended to improve noise immunity.
