• Product selling points: 1 This is a 5-bit high-precision digital tachymeter for measuring speed/frequency dual-use products, high precision frequency measurement, up to zero ‰ at 25 levels Celsius, resolution up to zero 2 Can be driven to produce pulse signals, can be connected to external sensors, recognizable indicators are: dry contacts, NPN, PNP, pulse and so on three Wide voltage DC3-15V, would be flexibly set crossover frequency value, as long as the pulse sign can give all motors can be pace measurement 4 key within the frequency and speed of the two modes of operation switching, operating mode strength failure memory, key in line with various needs to set the crossover frequency value, crossover frequency cost can be set 1-99999 and zero equipment crossover frequency value power failure reminiscence five Wide frequency dimension range, 0 6 Range automatic switching, from zero (R/M) to 000 (KR/M) 7 Reverse connection protection, advantageous and damaging lines related to the incorrect no longer burn, measuring sign amplitude of 3-30V, more than this parameter could also be damaged Product Description: New upgraded tachometer (frequency two) huge voltage DC3-15V, recognizable alerts are: dry contacts, NPN, PNP, pulse, etc, the sign amplitude of 3-30V, the variety of pulses (signal frequency high / low) and the rotational pace proportional to the relationship between the rate of the motor, so the speed of the motor and the motor&;s energy has nothing to do with the size of the external type, as lengthy because it can give the rate of the heartbeat indicators are ready to speed measurement, the speed of the signal can be the motor force straight provided, or could be an external sensor The speed signal could be supplied directly through the motor driver or through external sensors The meter head adopts industrial-grade high-speed MCU, strong anti-interference, stable and reliable, extensive measurement range, high dimension accuracy, the software adopts the leading full-synchronous cycle size method, applicable to all motors on the market that will provide velocity signal pulse output Main performance indicators: Display digits: 5-bit LED digital tube exhibit Refresh rate: sign frequency >3HZ: three times/sec; sign frequency ≤3HZ: roughly equivalent to the signal frequency Overflow display: "- - - -" Measurement accuracy: 0%±1digit or 0% at 25℃ Measurement range: 0, 9r-999/m Measurement method: complete synchronization cycle dimension method Input resistance: 100KΩ/resistive Power supply: default DC3-15V Voltage resistance: AC2000V 1min between exterior terminals and housing Vibration resistance: vibration number:10-55HZ, acceleration 50m/s² X, Y, Z route every single 5minX10 Operating environment (temperature and humidity): temperature 10C-+70C relative humidity 25-85% (no condensation) Storage temperature: -20℃-+80℃ (no condensation) Shell size: 79*42*26MM Opening size: 76*39MM Setting instructions: 1 There are 5 strains in the meter head, yellow is the signal line, the opposite two teams of pink and black lines is the ability delivery line, favor anybody organization of purple and black line strength delivery can be (more than one organization of crimson and black strength supply line is convenient to exterior sensors strength supply), the crimson line for the 3-15V high quality strength supply, the black line for the ground line, the meter head energy line and the signal line are linked to the kit to be measured 2 Measurement of speed, frequency mode selection, the again of the desk head "M" mode "S" number of the 2 keys, power to the measurement state, first short press the M key once to go into the mode alternative interface, the reveal solely shows the right facet of the 1st 8 words, which might be finished by means of a continuing short press of the S key The reveal can be in 0 1 2 three four modes cycle switching, display 0 dimension frequency wave mode, show 1 size pace wave, show 2 size frequency with out wave, demonstrate 3 dimension speed with out wave, according to their own actual need to choose a mode, no operation watch for about 4 seconds will automatically save the settings, and return to the state of pending measurements 3 Crossover price setting, earlier than atmosphere the crossover cost first perceive the thought of crossover value: the variety of pulse indicators taken by the turntable or the gear to show a circle within the velocity measurement, equivalent to exterior NPN type Hall proximity sensors or photoelectric sensors, the turntable or the equipment to show a circle to provide a pulse signal, the crossover price of the crossover cost that is, set up 1 would be With the store with velocity pulse signal output of the three-phase brushless drive or the marketplace 6-step commutation brushless power with out extra sensors, speed size settings are as follows, the power board velocity pulse sign output is straight connected to the meter head sign input and the proper energy supply, per the system of the motor poles * 3, similar to the motor has two poles, that crossover frequency price set (2 * three = 6) that is, 6 could be Measure the frequency environment method as above, akin to measuring the real-time frequency value, the mode selected within the measurement of frequency mode, the crossover frequency price set 1 at the line, the unit is HZ / sec, comparable to 1,000 HZ exhibit format for 01000, there is a dimension of the special frequency crossover frequency price can be set up per their own needs within the dimension of the rate of the mode, the unit of rpm, the demonstrate can be proven in the 5 eight words, such as 5,000 rpm reveal format for 05000, the very best show of 99999 If greater than 100,000 rpm, the decimal point might be shifted routinely to expose how many thousands of rpm, comparable to displaying 200,000 rpm, the layout is 2 hundred (200*1000=200,000) Power on to be measured first short press the S key once, enter the crossover cost surroundings interface, the demonstrate flashes, after which brief press the S key, the function of the S key for the five 8-word shift selection, wish to replace the 8-word, by way of brief press the S key to shift to which 8-word, and the 8-word can be flashing, after which short press the M key to alter the worth of the size of the 8-word, so that throughout the S key to shift selected to change the worth of the 8-word, after which replace the worth of the 8-word during the M key Shift the worth of the chosen 8 words, in the course of the M S two-key mixture set, whole the crossover frequency cost price set, if you wish to set the crossover frequency cost of 3, simply replace the first 8 phrases to 3 at the appropriate aspect of the show set up the impact of 00003, set up, no operation, watch for 7 seconds to automatically save the settings and return to wait for the measurement state Crossover frequency cost needs to be in 1-99999 or in 0 numbers, different values are invalid If the crossover frequency cost needs to set the decimal point, the tactic is as follows: in the crossover frequency cost atmosphere interface, throughout the quick press S key to shift to the correct aspect of the display, the lower right corner of the decimal point in order that it's lit, at this time a continual short press on the M key can be able to activate or off the left aspect of the 1st 8 phrases under the decimal point, (if the decimal point is brilliant on the opening of the decimal point, is not shiny is closed to the decimal point) set up, no operation, look ahead to 7 seconds to automatically save the settings and return to attend for the size state and return to the ready size state Table head environment operation video: Brushless motor methods to decide the motor pole pair video: Attention: 1 It ought to be used within the parameters of this meter and in usual environment 2 Set the mode wisely according to the actual use standards Set the crossover frequency price wisely 3 exterior excessive voltage signal, Jianyi don&;t operate with electricity don&;t touch the chip and components at the board by hand Shipping
