IRD Mechanalysis 198 Lasertach

IRD Mechanalysis Model 198 (also listed as 198F) is a compact laser tachometer used for speed measurement in industrial machines. The unit is now obsolete; replacement parts and factory calibration are no longer available, so most failures stem from aging opto‑sensor elements or degraded power supply circuitry. First‑check diagnostics should include verifying the 24 V DC input, inspecting the laser diode/photodiode assembly for contamination or breakage, and confirming that the tach output signal matches expected frequency ranges; also review any stored error codes on the display panel.[oss-gpt-20b]
