Make Up Replenishment Operating Notes Equipment

(B). Replenishment
(1) base on ampere-minute calculation ( just for reference)
    record the current (ampere) & plating time (minute) used for every application. Calculate according to formula Ampere X Minute (Am) Every 250Am required one gram Rhodium replenishment (20ml RD-A1)
 
  (2) Analyze Rhodium contain regularly and replenish accordingly.
 
  Note: Ampere-minute calculation method is only a rough estimation. Variation of replenishment is due to extra loss due to drag-out loss and variation of cathode efficiency. Keep the Rhodium content within 10% range and replenish acid by AR grade material only.
