Press “RST”
key for 3s
Select the counting frequency: 30, 300, 1000, 3000(Hz),press “ ” to select
Input mode: In-A,In-B (Press “ ” to selsect)
Output mode: N,F,C,A (Press “ ” to selsect)
a. Operation menu:
b. Convert displaying set value:
on the faceplate, “SET2” lamp “ON” means the displaying value is comparing output set value,“SET1” lamp “ON” means
counting value. Simply press “ ” key to convert set value and counting value.
e. Input modes selection: IN-A, IN-B
F. Output Mode selection: N, F, C, R
C. Modify set point(value):
first press “ ” key to convert to “SET2”, and follow below steps:
ENTER: press “ ” key to enter into set value modifying parameter, by entering, the highest digit will be flashing.
SETTING: press “ ” key to shift to the digit you want to modify, press “ ” to increase value of flashing digit.
QUIT: when value is modified, press “RST” key to quit the set point parameter, or 10s until automatically quit, counter will save the value modified.
d. Counting speed:
performance ability to restrain counting errors as follows:
* 3000 Hz ≤ 3000 Hz weak ( propitious to non-contact input) * 1000 Hz ≤ 1000 Hz common
* 300 Hz ≤ 300 Hz Strong * 30 Hz ≤ 30 Hz Strongest ( propitious to contact input)
7.OPERATION INSTRUCTIONS
Relay or transistor output delay time: 0~9.9s, only function for C and R auto-reset function,
Press“ ” to shift the digit, press “ ” to increase the (flashing digit) value.
press “Mode” key, then press “ ” key
press “Mode” key, then press “ ” key
press “Mode” key, then press “ ” key

1. Mode “A”: IN1: counting up input terminal (can used as independent signal input terminal)
IN2: GATE function; when input high voltage signals or short circuit with +12V, IN1 terminal input signals are restrained, counting value keep not
changed (like “S” poition in figure “ F1 ”) (A) must >the width of min.input signals (S) is the width of “IN2” input signals

1. Mode “N”: when the counting value equals to set value,
relay or transistor output, the counting value remains
unchanged until manual reset or external signal reset,after
reset, the counting start from zero.
2. Mode “F”: when the counting value equals to set value,
relay or transistor output, the counting value keep on
rising until manual reset or external signals reset, after
reset, the counting start from zero.
