1, speed frequency display switch (when the external high voltage signal this operation needs to disconnect the signal): (open the back cover, press the "S2" key, "0" for the frequency display plus filter, "1" for the speed display plus filter, "2" for the frequency display without filter, "3" for the frequency display without filter, "4" for the frequency display without filter, "5" for the frequency display without filter. "2" for frequency display without filter, "3" for speed display without filter, press "S1" key to switch. No exit key, wait 10 seconds to automatically return to the measurement state, or power off and restart to return to the measurement state.
2, crossover value setting (when the external high voltage signal, this operation needs to disconnect the signal): open the back cover, press the "S1" key, enter the crossover value setting interface, enter the interface, "S1" key is the shift key, "S2" key is the value plus key, the crossover value of the key. After entering the interface, "S1" key is the shift key, "S2" key is the value plus key, the crossover value must be set in 1-99999 or 0.0001-9.9999 numbers, other values are invalid, after setting the required crossover value by "S1" and "S2", wait 10 seconds to return to the measurement state automatically, or power off and restart to return to the measurement state. The measurement status is automatically returned after waiting for 10 seconds or restarted after power failure. Frequency division concept: the number of signals taken by one rotation of the gear. For example, the gear - turn to take 20 pulse signal, the crossover value that is set to 20 can be.
3, high and low voltage signal input switching (when the external high voltage signal, this operation needs to disconnect the signal): the factory signal input are set to low-voltage input, if you need a high-voltage input, you need to open the back cover to "L" at the short-circuit cap off. Note! When the short circuit is not disconnected and the high voltage input will cause damage to the instrument, and this damage is not covered by the warranty, please operate with caution. If you have any questions
If you have any questions, please consult the factory technology or distributor.
1. The instrument should be used in the normal operating environment.
2. Select the correct working mode according to the actual use requirements.
3. Set the frequency division value correctly.
4. The input signal should meet the requirements of impedance matching, and impedance transformation is appropriate for signals with large internal resistance.
5. Pay attention to operational safety when inputting high-voltage signals, do not set the instrument with signals.
6. Please do not touch the crystal and chip directly with your hands, human static electricity will damage the device and reduce performance.
