Rev.1.03 2005 JUN.
A digital indicator that controls measurement by
amplifying and performing high-speed digital
processing of subtle signals received from strain
gauge sensor that measures pressure, load or
torque. With the utilization of liquid crystal touch
panel display, visibility and operability of wave
profile display and others are greatly improved.
Through its ample 20-types wave profile
holding function, it is the best digital
indicator for graders and testers
used in results judgment of
assembling work and auto
machining.
Holding Functions
Provides assured support for force control and
assists quality control through its 2000
times/second high-speed processing and powerful
20-types wave profiles holding function.
Sample holding
Holds arbitrary point as of when the holding signal is received.
Timer specified range holding (Peak, bottom, P-P, mean)
A method that shifts the holding within the set timer (hold time) for
detect range upon activation of trigger.

Liquid Crystal Touch Panel
Display in Pursuit of
Visibility and Operability
Liquid crystal touch panel display that
had attained visibility and operability of
indicator display and wave profile display.
As a Super Signal
Conditioner
May also be used as a super signal
conditioner that outputs scaled analog
signal after digitalizing, filtering and
arithmetic processing of signals received
from sensor via its 2000 times/second
high-response D/A converter.
Wave Profile Display
Function
Wave profile display function that displays
real time input signal to wave profile
display and marks the holding points.
2000 times/second Highspeed Processing
High speed digital circuit and proprietary
programming technology that is able to
perform high-speed processing at 0.5ms
(2000 times/second) from the sensor
signal input moment until the control
signal output.
A Combination of 20-types
Holding Function
Various Interfaces (Option)
for Direct PLC Connection
Sample holding*, peak holding, bottom
holding, P-P (Peak to Peak), holding,
mean holding, external specified range
holding, (peak, bottom, P-P, mean),
timer specified range holding (peak,
bottom, P-P, mean), tr igger timer
specified range holding (Peak, bottom,
P-P, mean), minimum value holding,
maximum value holding and point of
inflection holding* that can quickly detect
required points for analog wave profile.

RS-485 Interface
DeviceNet Interface
CC-Link Interface
BCD Parallel Data Output
D/A Converter
Multi-holding Function
Multi-holding function that records up to
16-types holdings and comparison
settings and that is able to perform wave
profile control and changeover at any
time to any type through its external
pulsing signal. Only F371 can records
graphic settings.
Alarm Mode
Able to monitor at real time if the
indicated value during the holding is
abnormal or otherwise.
Additional Helpful
Functions for F371
Analog Monitor Output
Proportional voltage output
accordance to input signal.
Output level for every 1 mV/V output
is app. 2V. With this, regardless to
the non-use of holding function, input
wave profile can be record by the
recorder.
Multi-Calibration Function
Multi-calibration that can record up
to 4-types of calibration values and
able to changeover at any time to
any type through its external pulsing
signal.
