the model 856 is an auto-ranging 4.5 digit digital multimeter. this portable dmm has all of the conventional voltage, current, resistance, continuity and diode measurement functions. some of the additional standard features are comparison of measured results, frequency measurement and bargraph display and calculated functions for deviation, relative and decibel measurements. ac voltage and current measurements are made via a true rms measurement technique. the 3-level comparator allows measured results to be displayed as high, go or low with respect to preset upper and lower limits. ac voltage readings can be displayed in dbm or db relative to an arbitrary level. the large green led display is easy to read and gentle on the eyes.

key features
comparator function results (hi, go, lo) as well as dbm, db indicator.
4.5 digit 7-segment led readout.
auto range and up-down, manual range se-lectors.
bargraph display gives a visual indication of the range se-lected.
recessed and protected input jacks.
operation se-lectors: start/stop for use with the comparator function: compare sets up the comparison function; se-lect se-lects either the results or value of the deviation measurement function. it is also used to se-lect dbm or db in the db function; gpib (option) se-lects local or gpib control; keylock locks the se-lected operation; relative sets up deviation measurements; hold holds the reading when pressed.
function keys se-lect dca or v, aca or v, w , diode test, audible continuity or frequency.
