• 【 Input Counting Method 】: The rising edge means that the level rises from 0V to the peak value of the pulse, and the counter is incremented by 1. A falling edge indicates that the input level falls to the OV counter and increments by 1.Jump means that as long as the input level jumps up and down, the counter is incremented by 1. Long press【 IN 】 to clear the count
• 【 Frequency Mode Operation Instructions 】: The input frequency range is 0~9999Hz, which cannot be selected, and the displayed decimal point is automatically shifted.The output frequency range can be switched by pressing【 OUT 】 when the main interface【 FN 】 is white
• 【 Operating Instructions In PWM Mode 】: PWM displays two parameters, the frequency value (that is, the period value) and the duty cycle.The frequency value will be displayed in the original engineering quantity position (no engineering quantity display).Note that the maximum frequency does not exceed 9999Hz.The frequency value/duty cycle parameters can be set when outputting.When the main interface【 FN 】 is white, press【 OUT 】 to switch, there is a yellow cursor indication

【 Operating Instructions For Speed Mode 】:

1. The speed mode is used to calculate the speed of the motor or gear. One revolution of the motor or gear produces 1 pulse, one minute is 3000 revolutions, so 1 second is 50 pulses
2. 【 Time Unit 】: Frequency=RPS(per second)number of pulses per revolution, RPM(per minute)=RPS60, RPH(per hour)=RPS*3600.In the speed setting selection, note that the maximum frequency does not exceed 9999Hz

Select the 24V label left and right in the OUT signal type interface to enter this function state.In this state, displays the output 24V loop current on the main interface.Unlimited input signal detection type

1. Loop 1: After starting the output, 24V voltage is output between the (OUT) port and (COM) port, and the loop current is detected at the same time, and the current is displayed in the “output 24V loop” area.This function can be used to test, for example, pneumatic control valves or two-wire transmitters, supply them with 24V power supply and detect current
2. Loop 2: After activating the independent 24V power supply.The (IN-) port outputs 24V voltage between the (24V) port and the (COM) port.It does not affect the detection type of the input signal by the (IN+) port.In this case, select mA for the input signal type.Then the (IN-) port can be combined with the (IN+) port to form a 24V output,And at the same time detect the current loop.The function is similar to the circuit one
3. Port (IN-) can be switched to independent 24V power supply function.It outputs a single DC24V voltage, which is the (24V) port at this time.(24V) port used with (IN+) to test two-wire transmitters

Notice!

1. The difference between 24V loop detection and standalone 24V is:24V loop detection output signal port to measure feedback current.
2. Independent 24V port and output port can form 24V power supply,It can also be combined with the input (+) to form a transmitter to supply power and measure the feedback current of the transmitter
