【Display Unit】
When the main unit is set to "g", available values of [Display Unit] include:
"g", "mlb", "mN", and "Pa".
When the main unit is set to "kg", available values of [Display Unit] include:
"kg", "lb", "N", and "KPa".
When the main unit is set to "t", available values of [Display Unit] include:
"t", "klb", "kN", and "MPa".
【Force Area】
When [Display Unit] is set to "Pa", "KPa", or "MPa", [Force Area] will
involve in calculation.
Note: Pressure test result will be accurate only when [Force Area] is set.
【Zero Tracking】
Available values include "shutdown", "1d", "2d", "3d", "4d", and "5d".
Before the zero point becomes stable, values smaller than [Zero Tracking]
are automatically cleared. After the test values become stable, test frequency is
once per second. Variants of the test values that are smaller than [Zero Tracking]
are automatically cleared, to hold the displayed values.
【Sampling Speed】
When it is set to "6Hz ~ 1600Hz", it indicates force sampling speed per
second.
Note: The higher the sampling speed, the lower the test accuracy. Higher
sampling speed applies to dynamic and transient test; and lower sampling speed
applies to static and slow test.
【Calibrate Grav】The Gravity of calibration place adding speed
【User Gravity】The Gravity of Using place adding the speed
Its value is "9.600 ~ 9.900" N/Kg.
This parameter is used for gravity correction. The displayed value = test
value + test value * ([Calibrate Grav] –[User Gravity]).
【Alarm Upper LV】For setting alarm upper limit value.
【Alarm Lower LV】For setting alarm lower limit value.
- 14 -

【Alarm mode】
Values of this parameter include "Within", "Beyond", "Fracture", and "Shut
Off"; they are indicative of within limit alarm, beyond limit alarm, fracture alarm,
and shutoff alarm.
If the value is set to "Within" or "Beyond", when the alarm value is
exceeded, the buzzer acts while the display shows alarm information. Meanwhile,
the Boolean value is output. The following figure shows differences between
within limit alarm and beyond limit alarm.
If the value is set to "Fracture", [Alarm Upper LV]and [Alarm Lower LV]
will be automatically switched to [Fracture Alarm] and [Fracture Dead]. Set
these two parameters. When the force variation is reduced to the set value, the
buzzer acts while the display shows alarm information. Meanwhile, the upper
Boolean value is output.
Note: To use output ports, connect the power adapter first. The two SC
open-collector level outputs drive the DC 12V relay or the solenoid to act, each
output being 50mA.
【Peak V. Hold】a switch for enabling peak hold function
Its values include "on" and "off".
If this parameter is set to "off", the peak value will not be displayed on the
interface.
【External Input】external switch for enabling capture
Its values include "on" and "off".
- 15 -

When this parameter is set to "on", enabling the external switch (equivalent
to the "curve capture" button or the "curve capture" instruction) to be turned on,
the force gauge will enter curve capture mode. Note: capture time length is
subject to the sampling speed. Capture time (unit: second) = number of captured
data / sampling speed
【Peak Hold Time】
Its values include "Clr by Key" and "1 ~ 60 sec".
When this parameter is set to "Clr by Key", the peak remains unchanged
until users press the "Peak Clearing" button or "Zero Set" button. When this
parameter is set to "1 ~ 60 sec", the peak will be automatically re-measured after
the set time is up. The peak can also be re-measured by manually pressing the
"Peak Clearing" button or "Zero Set" button.
【Capture Lenght】
Set range: 1 ~ 1280 seconds
This parameter indicates the curve capture time in capture mode. The
capture time depends on the sampling speed: 60Hz: 1 ~ 1280sec; 12Hz: 1 ~
640sec; 25Hz: 1 ~ 320sec; 50Hz: 1 ~ 160sec; 100Hz: 1 ~ 80sec; 200Hz: 1 ~
40sec; 400Hz: 1 ~ 20sec; 800Hz: 1 ~ 10sec; 1600Hz: 1 ~ 5sec.
【Capture Trigge】
Set range: –99999 ~ +99999
The [F/P Boundary] parameter serves as a condition of triggering capture
after the force gauge enters the curve capture mode. If the number of data
captured reaches utmost or capture is stopped in advance, a capture report will be
generated and saved. The curve will be cleared after the force gauge exits the
capture mode.
【F/P Bounbary】first peak boundary
Set range: 1 ~ 99999
This parameter is used for determining first peak during peak test. Take the
assumption that the criteria for determining a peak is 10. After users press the
"Peak Re-measuring" button, a new peak test is started. During the test,
- 16 -

peak-to-peak (Vmax), valley-to-peak (Vmin), and new peak (Vnew) are updated
continuously. If the absolute value of (Vmax –Vnew) or (Vmin –Vnew) is
larger than 10, Vmax or Vmin is considered the first peak.
【Buad Rate】serial port baud rate
Set range: 4800 ~ 230400bps
Format: 1 initial bit; 8 data bits; 1 stop bit. No parity bit. This parameter will
take effect after users restart the force gauge.
Note: In order to ensure that each data is sampled during communication
with a PC, baud rate is recommended to set as follows: 6Hz: ≥4800bps; 12Hz: ≥
9600bps; 25Hz: ≥14400bps; 50Hz: ≥19200bps; 100Hz: ≥28800bps; 200Hz: ≥
38400bps; 400Hz: ≥57600bps; 800Hz: ≥115200bps; 1600Hz: ≥230400bps.
Due to speed limits of serial ports, if the sampling speed is larger than 400Hz,
data will be lost when it is transmitted to a PC. Instrument reading results prevail.
【Serial Port】serial port output way
This parameter is used for controlling real-time data transmission.
Parameter values and meanings are as follows:
Prohibit: The serial port is forbidden to transmit real-time data.
Key/Order:When the button is pressed or an output command is
received, output is performed once. If the force gauge is connected to a PC, PC
programs will automatically forbid the output function.
Change: When test data changes, output is performed once.
Stabilize: When test data becomes stable, output is performed once.
Consecutive: Test data is transmitted uninterruptedly.
【Display Angle】
This parameter is used for changing display angle. Available values are 0°
and 180°.
【Auto Power Off】
This is an energy-saving design. When the force gauge is idled for a
specified period, it will automatically shut down.
- 17 -

【Auto Backlight】
This is an energy-saving design. When the force gauge is idled for a
specified period, it will automatically adjust backlight brightness.
【Clear Storage】clearing stored data
This parameter is used for clearing stored test reports and curves. When
stored data is overflowed, the system will automatically clear all data and begin
storing new captured data.
【Reset User Set】reset parameters
this parameter is used for restoring factory settings in case of wrong setting
or other setting problems.
【Language】Chinese/English switchover
【Factory Set A\B\C】【Factory adjustment and self-test】
This parameter is used only during factory setting. Users are not authorized
to set this parameter.
【Connection】
This parameter is provided to users for connector wiring. Users can refer to
it during connector wiring.
【S/N】local sequence number
This parameter indicates internal sequence number of the machine. Users
are not authorized to set this parameter.
