F350 is a digital indicator that is capable of two-channel inputs of strain gauge type sensors. Equipped with calculation functions, such as ch1+ch2, ch1-ch2, F350 is ideal for total, difference, balance and other load measurements.
Calculation and judgment outputs can be made for 2ch input values of strain gauge type sensors. Calculated value is displayed on the main display, and ch1 and ch2 input values are displayed on the sub display.
● ch1 + ch2: The ch1 value and ch2 value are added.
● ch1 – ch2: The ch2 value is subtracted from the ch1 value.
● |ch1 – ch2|: The absolute value of the difference between the ch1 value and ch2 value is calculated.
● High select: The ch1 value or ch2 value, whichever is larger, is selected.
● Low select: The ch1 value or ch2 value, whichever is smaller, is selected.
● Calculation value: HI, OK, LO
● ch1 value: HI, LO, Alarm output
● ch2 value: HI, LO, Alarm output
Including the high-speed CPU that allows processing from sensor inputs to outputs at 3000 times/sec., F350 captures necessary points reliably. (The speed can be switched to 300 times/sec.)
The indicated value can be zeroed by key operation. F350 is also equipped with the function of subtracting a set value from the indicated value. This function is convenient in the case where a no-load condition cannot be set up or for offsetting.
Voltage in proportion to the input signal, which is useful for recording with a recorder, etc., can be output on each channel.
Timing at which HI/LO limit comparison is made can be provided with a margin. This function is effective to prevent chattering, etc..
HI and LO limit output time chart (calculated value) Only HI and LO outputs are made on ch1 and ch2.
F350 is equipped with hold functions of calculated values (Sample, Peak, Valley, Average). Section setting can also be made by external signal.
Example 1) Sample hold
Example 2) All section peak hold
Example 3) Externally specified section average hold
Load and pressure are controlled at high speed with high accuracy.
