A 0.40mm drill is recommended Drill part no. DM2R INSTALLATION The receptacles of the replaceable microprobes feature a collar at the top of the tube, which is used as a stop in the fitment process. Due to the minute tube diameters and thin walls, it is imperative that the drilled hole diameter & straightness are very accurate. It is recommended that the pre-wired option is taken - as connecting a cable to these receptacles is an extremely delicate operation. Usually, multi-plate fixtures containing no less than 3 plates, are used to retain multiples of receptacles. Otherwise a block of stable material which will allow reliable drilled holes is to be recommended, with the receptacle fitted wire/tail first with tweezers. A small amount of locking compound may be required on the barrel to secure it. Then the microprobe may be pushed into the receptacle, tail first, using the tweezers, making sure light pressure is put onto the probe's collar, not onto the fragile plunger.
