Keypad set up of the parameters in the Tachometer:
Select functions: There are 4 modes in CTT, (left to right) timer, counter, tachometer and timer + counter.
–FunC
Cont taCh –mixtime
Select rotation speed: Maximum 10Kcps; others 5K, 1K, 200, 30 and 1cps.
C–Sped
–10k ––5k ––1k –200 ––30
–point
Set up the position of decimal point: 0 (no decimal point), 1 (one digit after decimal point), 2 (two digits after decimal
point), 3 (three digits after decimal point).

psCale
Set up pre-scale value: 1.000 (default 1:1) Range: 0.001 to 99.999
St–taC
Set up the delay time after switching on the power: 0.0 (default). The tachometer will start to run when the set delay
time is due after the power is switched on. Setup range: 0.1 to 99.9 seconds
––00
St–Av6
Set up average value of the input filter: The average value is for making the present value detected by the tachometer
more stable.
The setup range is 0 to 3 (1 = 2 data, 2 = 4 data, 3 = 8 data). For example, if you select “3”, the system will
average the 8 present values from the tachometer to make the present value displayed on the screen more stable.
–rtsr
Set up minimum width of reset signal: Default = 20ms; 1ms is also selectable.
––20 –––1
Select output modes: There are 4 output modes, 2Lo1Lo, 2Lo1Hi, 2Hi1Lo, and 2Hi1Hi, For example, when you select
1Hi1Lo, and assume the first set value is 100 (2Hi) and the second 50 (1Lo), the output value of the tachometer will be
below 100 (2Hi) and above 50 (1Lo) and CTT will not perform an output. If the set value exceeds the range, CTT will
perform an output.
