RUNCCI-YUN Mini Digital Voltmeter 0.28 inch Three-Wire DC 0-100V Voltage Gauge Tester, LED Mini Voltmeter Digital Voltage Display Panel Meter (5Pcs)

• ★★ [Excellent quality] Digital voltmeter DC 0-100V 0.28 inch three-wire voltage tester, mounting hole: 23 * 10 mm.
• ★★ [Detection voltage] DC0-100V; working voltage: 4.0-30V; working current: <20mA; detection rate: ≥200mS/time; accuracy: 3‰ (+/- 1 word); working temperature: -10~+65 ℃.
• ★★[Protection design] Reverse polarity protection. If reverse polarity is applied, the meter will not burn out, but the screen will not display anything.
• ★★ [Ultra high precision] Precise automatic adjustment, when it is less than 10V, it is accurate to 0.01V, and when it is greater than 10V, it is accurate to 0.1V.
• ★★ [Calibrateable] The screw on the back can be adjusted for calibration, turning clockwise to low voltage.
