HR390 Milliohm Meter Case
Description
I Created This Case For An Hr390 Milliohm Meter Board From China, Which Came Without A Case. It Is Assumed That The Hr390 Board Is Attached To A 1602A Lcd Display Board. To Complete The Assembly, You'Ll Need To Add A Few Additional Components: - 9V Battery Connector (And A 9V Battery). - Slider Power Switch Ss-12F16 (And Some Wires To Connect It) And 2Mm Screws Or Glue To Hold It In Place. - 5 M3X6Mm Screws To Screw The Two Halves Of The Case Together And To Attach The 9V Battery Cover. The 4 Original Brass Standoffs (Which Come With Most Hr390 Boards) Are Unused But The Screws Can Be Repurposed For This Case. - Probes (Mine Came With Some Alligator Clips But They Were Slippery Suckers So I Used Some Others) Plastic Pins Are Used To Hold The Boards In Place, Eliminating The Need For Screws Inside The Case. The On/Off Slider Switch Is Expected To Be Screwed Into The Top Half Of The Case, Or Could Also Be Hot-Glued. Push Buttons For Function & Calibrate Should Be Inserted Into The Top Half, And Probe Wires Fed Through Openings, Before Attaching The Two Halves Together. Make Sure The Connector Pins Line Up When The Two Halves Are Assembled. The Hr390 Milliohm Meter Was Much Cheaper Than Other Instruments For Measuring Resistances Less Than 1 Ohm, But Originally Didn'T Come With A Case. Scad File Included For Customization/Remixing.
