Features - Sony LY51 Instruction Manual

2. FEATURES

(1) High-reliability zero point reference function
Once the zero point is loaded, this function checks the value
every time the zero point is passed. If the position value fails
to correspond for 3 counts or more, the unit will send an alarm
signal to inform of the error.
Using this alarm signal, count mis-operation damage due to
error counting is kept to a minimum. (This function can be
enabled and disabled.)
(2) Peak hold function useful for counting up measured
data
This function holds the maximum, minimum and peak-to-peak
values during measurement. (The unit can execute this
function even while it performs the optional comparator
function.)
(3) Various external input functions for automatic
measurement
The unit has external reset, external recall and universal
contact point inputs which enable operation by external input
signals (contact point). This allows the unit to be used for
automatic measurement. (The universal input can be used
to input various signals according to the initial settings.)
(4) Easy system assembly by rack mounting
The counter is designed for standard installation in a rack,
making it easy to assemble in a system.
(5) Selectable display resolution
You can select the most suitable display resolution. However,
the selectable resolutions vary depending on the input scale
unit.
(6) Data storage function
The display resolution and other initial setting values are
stored even after you turn off the power. Therefore, once
these values are set, they do not need to be set again next
time you use the unit.
The preset value, current value and other data are also stored
even after you turn off the power. You do not need to set the
data next time you use the unit. (The current value storage
function can be enabled and disabled.)
(7) Collective automatic setting of initial setting items
Various initial setting items can be input using a specification
code. This allows various setting items to be determined
automatically at once. (Initial settings can also be input
individually.)
(8) Abundant output functions
Up to 3 optional I/O units can be inserted to support a wide
variety of measuring systems.

BCD output (option)
You can retrieve various data by BCD output using the
optional BCD unit LZ51-B. (Current, maximum, minimum
and peak-to-peak values)
