Tachometer & frequency in one
Optionbuzzer alarm Relay control alarm level output(High level of the output signal is an effective alarm signal)
The meter can be set rate K1, rate K2, and decimal point dot
Measurement display value = input value x K1/K2
With digital filtering function, Strong anti-interferene ability.
Parameter Tables:
Parameter setting:
Press and hold "MODE" button, then press "SET" button to enter parameter setting, the symbol of current parameter will show on the display
Press "SET" button repeatedly to switch to the next parameter setting.
If setting is needed, release all the buttons, press " MODE" button again to enter the parameter setting.
Press "MODE" button repeatedly to switch the flash position, press "SET" button repeatedly to increase.
After setting finished, press and hold " MODE", then press " SET" button to confirm. After all parameter settings done, exit this mode.
It will exit automatically if no button pressed within 60 seconds.
Parameter specification:
t y p e (Type)--Function selection, "0" for Frequency Meter, "1" for tachometer ( unit: revolution/min)
d ot(Dot)-- For decimal point places selection 0: 0 1: 0.0 2:0.00 3:0.000
filter(FLtr)--Digital filtering time constant (Range: 1~10)
Using the digital filtering to overcome the fluctuation of input signal. The consumers will select appropriate filtering constant
according to the frequency & magnitude of the fluctuation of signal If the displayed value jumps significantly please increase the setting value
The use of rate K1 K2 adjusting display value,Display value= measuring value x K1÷ K2
Alarm output action type (Please remark when placing order)
Input pulse signal: switching quantity, level pulse
instruction of wiring: (see on the label of back of meter)
"-- PW++"are respectively serves as the negative and positive input terminals for power supply to the meter.
"iN" is the positive input terminal of the measurement signal. In addition, the negative input terminal VF- of the measurement signal is connected to the power supply negative terminal of the meter (Except for the isolated power supply version).
Relay control: CM "is the common contact, "NO "is the normally open contact, and NC "is the normally closed contac.
VF+ is the Positive pole of feed output (Default output is DC5V/30mA, other voltages can be ).
VF - is the negative pole of the feed output and the common terminal of the signal input.
Working conditions:
Operating temperature: -10 ~ +50
Working humidity: 10 ~ 80% (no condensation)
Working pressure: 80 ~ 106kPa
Sun exposure: no direct exposure
