Model PM-45X and PM-45XU Precision Panel Meter

The PM-45X and PM-45XU are truly unique and extremely versatile instruments. Believed to be the world’s smallest and most energy efficient 4 1/2 Digit LCD Panel Meters, they nevertheless offer more high performance features than most larger and more expensive DPM’s. Both meters incorporate a crystal controlled 100KHz clock that provides an exceptionally high normal mode rejection of 120dB at multiples of 50/60Hz. Bipolar differential and singleended DC voltages from ±199.99mV to ±1200.0V full scale can be measured and scaled in almost any known engineering unit. Provision has been made for signal offsetting and the capability of attenuating both high and low signal inputs. Resolution is 10?V over ±19999 counts, and errors due to zero drift are virtually eliminated by autozeroing. Other modes of operation, selectable by the user, include an ohmmeter mode, current meter mode and ratiometric mode.
