0.28 small Blue digital voltmeter 2 wires DC2.40-30 Bule 

功能簡(jiǎn)介

1.量程：2.4-30V(紅色） 2.6-30V（黃）2.6-30V(綠） 3.2-30V(藍(lán)）

2.配有兩根導(dǎo)線，接線方便簡(jiǎn)單，方便接入汽車(chē)/電瓶車(chē)/摩托車(chē)車(chē)內(nèi)線路

3.具有反接保護(hù)功能，線接反不會(huì)燒毀，本產(chǎn)品具有微調(diào)功能

4.注意使用最高輸入電壓不能超過(guò)30V.否則有燒毀的危險(xiǎn)

5.在電壓低于3.0V時(shí)，顯示亮度會(huì)變暗，但不影響正常測(cè)量。

6.在測(cè)量10V以下電壓時(shí)，小數(shù)點(diǎn)后顯示兩位；在測(cè)量10V以上電壓時(shí)，小數(shù)點(diǎn)后顯示一位。既能照顧到電池用戶(hù)的對(duì)測(cè)量精度的需要，又能照顧到測(cè)量更高電壓的需要。

Introduction to features

1. Range: 2.4-30V (red) 2.6-30V (yellow) 2.6-30V (green) 3.2-30V (blue)

2. With two wires, wiring is simple and easy to access the car / battery car / motorcycle car line

3. With reverse protection function, the line will not burn back, this product has fine-tuning function

4. Note that the maximum input voltage can not exceed 30 V. Otherwise, there is a risk of burning

5. When the voltage is lower than 3.0V, the display brightness will darken, but does not affect the normal measurement.

6. When measuring the voltage below 10V, two digits are displayed after the decimal point. When measuring the voltage above 10V, one digit is displayed after the decimal point. Both to take care of the battery user's need for measurement accuracy, but also to take into account the need to measure higher voltage.
