1. KH-965 multimeter is used to measure DC power, one-way voltage and AC voltage, measuring resistance is an indispensable test equipment for the unqualified. Any electrical maintenance technician.2. Multimeter has four main functions: measuring resistance, measuring DC voltage, measuring AC voltage and measuring current.3. KH-965 multimeter long life, stable, knob can be flexible to adjust the scale, so that your electronic equipment maintenance process is simple and effective.4. When measuring AC voltage, we switch the scale to AC scale, so that the AC scale is one step larger than the voltage to be measured. For example, if you are measuring AC220V voltage, we will keep the AC 250V scale, if we keep it on the step of the voltage to be measured, the clock indicator pointer dramatic, if the bar is too large, the indicator pointer is not accurate.Name:KH-965 multimeterPower Supply:2 x AA batteries or 1 x 9V batteries (Not included batteries)Colour:GrayMaterial:ABSSize:16.5x14x5cmPackage Contents:1 x Multimeter2 x test leads1 x English instruction manualOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
