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).
(POSITIVE FOR DC POWER)
(NEGATIVE FOR DC POWER)
EXAMPLE : MAXIMUM VALUE OF 1.500 COUNTS,
THAT DECREASES TO 300 COUNTS.
THE TIME THAT THE READING OF 1.500 COUNTS,
WILL REMAIN ON THE DISPLAY, WILL BE :
23 - 5 = 18 MINUTES
