Hotplate Metal Heat/Stir.97069 (ES)

Hotplate Metal Heat/Stir.97069 (ES) PCB Testreas of the PCB are LIE during test. This procedure must only be followed by personnel competent at testing Mpins' rated products.Denotes optional test, to be checked in the event of PCB malfunctionVisual InspectionIl required components presentNo visible short circuits, solder bridses, etc.No musaligned / misplaced/unsoldered kees or pins.Check correct polarity of electrolytic capacitors, diodes, etc.Basie Electrical Tests• Resistance L-N:-3k0 ( Jummper in 230V positionMo•Resistance L1-LOAD:1Mо•Resistance D1(Pins -/AC Side) -12RFunctional Tests- Heat SectionConpect PCB to test fixture (See Diagram)Ensure jumper(s) correctly set for test supply voltage (115V /230V)Set S0C on thermocouple simmlator, or heat thermocouple to approx 50CPSU Operation 230V, 50Hz InputPOST:D3 ilbminates .
