An inexpensive r.m.s. ammeter for use with electrosurgical units.
A true r.m.s. reading rf ammeter utilizing low-cost integrated circuits has been developed for use in measurements of the power output and rf leakage of electrosurgical units. The meter is sufficiently accurate for most clinical applications without the drawbacks of the thermal ammeter.
