1-1. Main features of the F350

1 OUTLINE
The F350 is a digital indicator that is capable of two-channel inputs of strain gauge
sensors.
Calculations, such as addition and subtraction, and comparison judgments are made
by using the input values of two channels. The F350 is also suitable for balance
measurement.
The F350 is equipped with comparison judgments on the input value of each channel,
and analog voltage output.
The A/D conversion speed of each channel and the digital processing speed for
calculations and judgments are as high as 3,000 times/sec. It can also be switched to
300 times/sec.

4-1. How to calibration

4 CALIBRATION PROCEDURE
A data sheet will be attached to a strain gauge sensor you buy.
On the data seat, the following values are listed.
Capacity Rated Output
Non-Linearity Hysterisis
Input Resistance Output Resistance
Zero Balance etc.
The Capacity and the Rated Output are necessary values for the equivalent input
calibration. Input these two values to F350.
POINT
"Calibration" refers to an operation whereby matching between the F350 and a strain gauge sensor
is obtained. The F350 uses the two calibration methods as described below.

Equivalent input calibration

Calibration is performed without an actual load by entering the rated output value (mV/V) and the
capacity (to be indicated) of the strain-gage sensor by the keys. Calibration is easily performed
when no actual load is available.
For example,
for load 2.001mV/V-100.0kgf for pressure 2.002mV/V-10.00kgf/cm for torque 2.502mV/V-15.00kgf・m

4 CALIBRATION PROCEDURE

Chapter

2
Gain will be automatically decided by registering the values indicated as follows.

Actual load calibration

This approach provides calibration by applying an actual load to the strain gauge sensor and
inputting the actual load value. This calibration is without little errors and more correct.
CALIBRATION PROCEDURE
Perform either actual load calibration or equivalent input calibration.
23
*
If an actual load cannot be applied, make sure to perform equivalent input calibration
alone.

The equivalent input calibration and the calibration protect uses the following procedure :
Turn off the calibration protect that inhibits
calibration.
Set the excitation voltage according to the sensor
used.
Set the decimal place.
Set the desired minimum value of digital increments.
(This step may be omitted if there is no change.)
Set the zero point of the strain gauge sensor in no-
load condition (with the sensor unloaded).
Equivalent input calibration
Register the rated output value of the strain gauge sensor, and the indicated value of that time.
Actual load calibration
Set the span (gain) point of the strain gauge sensor with a load applied to the sensor.
The calibrated value can be offset in advance.
(When not using, set "0.")
Set the load limit that allows Digital Zero.

Zero calibration
Register the zero point with the sensor unloaded. Also, if there is any initial load, such as a jig, for
measurements, the zero point can be registered with the initial load applied, but the signal input
range needs to be considered as the initial load is subtracted from it. In addition, there is a way of considering the initial load by using the digital offset. See " ⑦Digital
offset" on page 31.
Setting value
-3.000+3.000mV/V
By performing zero calibration, the setting value of zero calibration becomes the sensor output
value (mV/V) of the time when it was executed. The load with which actual load calibration was
performed can be confirmed. However, it stays unchanged when an error occurs.

6-3. Hysteresis

This function is to allow a margin for timing at which HI/LO of the HI/LO limit comparison is
turned off. Normally, HI is turned on when the indicated value exceeds the HI limit and is turned off
when the indicated value falls below it. However, by setting the hysteresis, HI is turned off when
the indicated value falls below the HI limit further lowered by the hysteresis value. This function is
effective to prevent chattering (phenomenon in which signals repeat turning on/off immediately
after switching of relay contacts and switch contacts) in such a case where signals fluctuate
(vibrate) subtly.
The setting is common to the calculated value, ch1 value, and ch2 value, which operates
individually.

Average hold

The average of the sampling values over the specified section is calculated and updated, and then
held.
The section is specified by the setting of "all section," "external signal," or "external signal + time."
(Example) Externally specified section average value hold
t1: A delay time between the instant
when the SECTION signal is inputted and the instant when the value to be held is detected
Approximately 0.7ms (MAX.)
t2: A delay time between the instant when the SECTION signal is released and the instant when the value to be held
is determined Approximately 0.7ms (MAX.)
t3: A minimum reset signal width required for releasing the hold
Approximately 0.7ms (MIN.)
The delay time and signal width
expressed apply when the A/D conversion speed is 3000 times/sec. They become 10-times when the A/D
conversion speed is 300 times/sec.
The detection section is limited by the maximum average value detection time set according to the
Chapter
"average sample number." If the maximum average value detection time is exceeded, detection is
automatically terminated, and the average value of that time is held.
7

Average sample number

In the average hold, the maximum average value detection time for average processing by each
sampling depends on the A/D conversion speed as follows:
When the A/D conversion speed is 300 times/sec: 50sec.
When the A/D conversion speed is 3000 times/sec: 5sec.
Then, if this average sample number is set at 2 or more, the sampling data used for average
calculation becomes the representative value of the sampling values of the set number (average
obtained according to the number). By this setting, the average value detection time can be
elongated, but error causes by average calculation increase.
Example) When the A/D conversion speed is 3000 times/sec,
Maximum average value detection time = Average sample number × 10 sec.,
and also the number of average updates will decrease.
Number of average updates = 3000 times/sec. ÷ Average sample number

By this method, the hold detection section is specified by the T/H signal.
Detection starts with the T/H signal ON to perform each hold operation.
Control is performed simply by the T/H signal without using the SECTION signal.
Therefore, there are tracking sections and detection sections, but there are no hold deciding
sections.
(Example) All section peak hold
t1: A delay time between the instant when the T/H signal is inputted and
the instant when the indicated value is held
Approximately 0.7ms (MAX.)
t2: A delay time between the instant when the T/H signal is released and
the instant when the indicated value returns to
tracking Approximately 0.7ms (MAX.)
t3: A minimum reset signal width required for releasing the hold
Approximately 0.7ms (MIN.)
The delay time and signal width expressed apply when the A/D conversion speed is 3000 times/sec.
They become 10-times when the A/ D conversion speed is 300 times/sec.
NoteDuring the undetermined sections, the judging output varies with fluctuations in the input waveform.
However, the H/E output remains on during the undetermined sections. Read the judging result when the indicated value becomes stable (immediately before the T/H signal rises).

It is factory-set that each hold is automatically reset at the start of the detection section, and
therefore, simple control can be performed by one signal without releasing the hold.
However, when the auto reset functions, if the signal causes chattering, the point that should be
taken originally may deviate. Switching is provided so as to prevent the next detection from being
performed until the T/H signal is turned on even if the SECTION signal is turned on again.

A D/A converter is provided for obtaining analog output synchronized with the indicated value of
the F350.The analog output ranges are -10 - +10V output and 4 - 20mA constant-current output.
By using the D/A zero setting and D/A full scale setting functions, analog output can be obtained
between zero (0V, 4mA) and full scale (10V, 20mA) with respect to the predetermined digital value.
The output circuit and the main unit circuit are isolated.
The resolution is 1/10000 with respect to the ranges of -10 to +10V and of 4 to 20mA, and the
conversion speed follows the A/D conversion speed.
The maximum voltage output range are about ±11V, the maximum current output range are about
2.4 - 21.6 mA
