... The highly versatile DMS-EB has provisions for such common applications as attenuation of high input voltages, gain (span) and offset (zero) adjustments, 9/12V battery operation, and direct decimal point placement. The DMS-EB is compatible with all four versions of the DMS-30 and DMS-40 Series (±200mV, ±2V, ±20V and ±200V) making it interchangeable from meter to meter and application to application. Solder gaps conveniently placed on the board are easily bridged or cut confi ...

... Battery Operation section is rated for a 150mA LED meter or a 35mA backlit LCD meter. A 10μF/35V tantalum capacitor (C2) should be installed with the polarized end next to the + symbol on the DMS-EB. This is especially important if the power supply is located far from U1. 5. DMS-40 Meters: When the DMS-EB is used with DMS-40PC or DMS- 40LCD meters, be sure to open SG13 ...
