SPECIFICATIONS

THIS SYSTEM FOR MAXIMUM READING, IS AVAILABLE FOR

THOSE APPLICATIONS WHERE A SUDDEN SIGNAL DECREASE

IS PRODUCED. FOR EXAMPLE: TEST SAMPLES SYSTEM,

PRESSURE TESTS, COMPRESSION, STRENGTH, VACUUM,

ETC.

THIS SYSTEM OPERATES WHEN THE SIGNAL INPUT

DECREASES, GENERATING AN ORDER THAT BLOCKS

INSTANTANEOUSLY, THE PRESENT READING IN THE DISPLAY,

ACTING ON THE "HOLD" FUNCTION. THE DECIMAL POINT,

PLACED TO THE RIGHT SIDE, ILLUMINATES, (1XXX.), WHEN THE

DISPLAY IS INDICATING A PEAK (MAXIMUM VALUE).

PRESSING THE PUSHBUTTON RESET, THE FUNCTION "HOLD"

DISAPPEARS, AND THE DISPLAY CHANGES TO READ THE

CORRESPONDING VALUE OF THE INPUT SIGNAL.

THE TIME PERIOD, DURING WHICH THE "HOLD" FUNCTION

REMAINS ACTIVATED, DEPENDS ON THE SIGNAL INPUT

VARIATION, (DIFFERENCE BETWEEN THE PEAK VALUE AND

THE VALUE CORRESPONDING TO THE SUDDEN SIGNAL

DECREASE).

DECIMAL POINT, POINTER THAT THE
"HOLD" FUNCTION, IS ACTIVATED.
