Battery Drain Meter
Two models for measuring and displaying
hearing aid battery drain & voltage

Whether you are a hearing health provider in the office, or a hearing aid specialist working in a lab, battery drain is an important factor for you. The amount of electronic current a hearing aid circuit is drawing can tell you a lot about whether an instrument is working properly. Many times, units are evaluated in a matter of seconds by simply reading the battery drain. You can use a drain meter to simply power an instrument, so next time you need to listen to a hearing aid, why not plug it in to your drain meter and note the amount of current the hearing aid is drawing? After awhile, you will become experienced in using this measurement to confirm and diagnose problems.

 Lightning Enterprises manufactures two models of digital hearing aid battery drain meters. BDM-1 is a basic unit that measures and displays battery drain only, and BDM-2 which measures and displays battery drain plus DC voltage. Both units measure just 4 3/8" x 3 1/8" x 1 7/8", weigh about 1 lb, and are designed to sit on the bench-top.

 

BDM-1 hearing aid battery drain meter

BDM-1 - Measures hearing aid electrical current (battery drain)
BDM-1 battery drain meter supplies working voltage to a hearing aid while accurately displaying the amount of electronic current the hearing aid is drawing, commonly referred to as battery drain. BDM-1 connects to the hearing aid battery compartment through any industry standard battery pill, or probe / substitute (not included). The negative terminal supplied to the hearing aid is directly tied to earth ground for easy use with external test equipment which utilize a grounding electrical plug, such as an oscilloscope. Power requirements for the standard BDM-1 unit is 120V 60Hz. A 230V50 Hz version is also available.

BDM-2 hearing aid battery drain and DC volt meter

BDM-2 - Measures battery drain & DC voltage
BDM-2 Battery Drain & DC Volt Meter supplies working voltage to a hearing aid while accurately displaying the amount of electronic current the hearing aid is drawing, commonly referred to as battery drain. BDM-2 also functions as a digital DC volt meter using the supplied voltage probe. BDM-2 connects to the hearing aid battery compartment through any industry standard battery pill, or probe / substitute (not included). Only the positive voltage probe is needed as the negative is supplied to the hearing aid through the battery pill. The negative terminal is also directly tied to earth ground for easy use with external test equipment which utilize a grounding electrical plug, such as an oscilloscope. Power requirements for the standard BDM-1 unit is 120V 60Hz. A 230V50 Hz version is also available.
