Product Introduction
How to install it?
- Cut an 85mm (3 3/8") hole in the panel and allow a clearance of 70mm (2 3/4”) behind the panel to fit the gauge.
- Put the gauge in the hole.
- Using M4 nut and C type bracket to seal up the gauge.
How to connect wires?
Red wire --- Power Positive.
Black wire --- RPM Signal.
Orange wire (backlight) --- Power Positive.
Blue wire --- Power Negative.
Please note: Tachometer can be connected to 12VDC and 24VDC power directly.
Why Don't get RPM signal?
Tachometer sometimes cannot get signal by ignition system. So, I suggest Tacho sensor signal. It is more stable.
I suggest you can buy a Tacho sensor from Eling Parts. ASIN NO. is B07RR8NQ45, B07RN3HJ72.
How to be setting Tach RPM Ratio?
1. Turn on the power supply first.
2. Press and hold the mode button for 3 seconds to enter the setting speed ratio mode. then adjust speed ratio from 1-300 according to your request.
3. After setting, Data is automatically saved.
4. Please note: If your sensor is installed on the flying wheel panel, the RPM ratio is equal to the number of gears of the engine; If the speed signal takes from W-Terminal, the RPM ratio is equal to the half of the number of poles.
5. Normally, When the engine at idle state, tachometer shows 600-800rpm that means speed ratio is correct. If not, you can turn down or turn up speed ratio to check RPM difference.
Package Includes:
1x Tachometer
1x Multi-plug socket

I had a defective tachometer on my boat, so I decided to order a replacement. The new tachometer arrived promptly and I was able to install it on the second day. The calibration process was easy and went smoothly. I am very satisfied with my purchase.

No logré que funcionara, terminé comprando otro de la marca Bosch y me funcionó a la perfección.

Not clear (at least to me) that this tach will not work for a gasoline auto engine ,, no provision for tach signal from a distributor or ignition box. This relies on a turning signal from a rotating part.

Don’t waste your time or money. Wired up to the Alternator, yes it has a proper A/C tap. No matter what speed ratio you set it to, gauge spikes up to 5000 then down to 2000 and is terribly delayed. Contacted the seller and no support was offered for a replacement, or a solution other then buying their sensor even though it’s clearly stated it will work off an alternator. 0/5 stars. Will not buy again. There’s a reason it’s cheap compared to every other reputable brand IT DOES NOT WORK

Did not install right away, would not calibrate, re: number of cyl. Screen color, etc.

I installed the tacho, using the 12 v signal to the coil of a 4 cylinder 4 stroke engine the meter appears "sticky" and slow to respond = I have sent an email to check my installation is corect to the supplier - the supplier responded suggesting adding the sensor mentioned in the instructions.

Exactly my headline. This thing is useless. In the process of returning. The delay for an accurate reading is at least 2-3 seconds. I did get it adjusted to read the correct RPM, but any RPM changes and it's a snail to catch up. Does not serve the purpose of what a tach is meant for.

Looks fantastic, tach is accurate. We will see how long it lasts.

The face bezel is not very wide, so the hole needs to be cut fairly precisely. The tach looks good and appears from the outside to be well made. To get the correct RPM reading on my 2 stroke 2 cyclinder outboard motor, I tapped one of the wires from the magneto to the rectifier to use for the signal wire to the tach, and I set the ratio on the tach to 4.7. Too high a ratio, like 20 for example, would result in no needle movement, and too low a ratio, like 3 for example, would cause the needle to be far too responsive. The ratio setting is quite sensitive, so take the time to dial it in.

Never written a review before but I felt obligated since the review I read was so poor and the tach works perfectly. If I had anything bad to say it would be that the instructions/manual could be a little more English friendly. With the exception of that I am very happy with the gauge!
