Capacitance Meters, Ground Earth Resistance Tester Multifunction Digital Clamp Meter LCD Display Alarm Clamp Ammeter ST4100/ST4800(ST4800)

The clamp-shaped ground resistance tester is controlled by a microprocessor to accurately detect the ground resistance. It uses a rapid filtering technology to minimize the inteerence. It is a commonly used and necessary instrument for telecommunication, electric power, meteorology, engine room, oil field, electromechanical installation and maintenance as well as industrial enterprise departments using electric power.Features:Easy to Operate: When measuring ground system with loop, there is no need to disconnect the ground wire without auxiliary electrode, safer and faster. Precision Clamp Head Design: Using precision iron core and winding, stable, precise and strong anti-inteerence. Clamp Size: 1.26"(32mm), lar jaws with double insulation for extra safety.Data Stora Function: 500 sets of measurement results can be recorded, the "MEM" stora indication, flashing the "MEM" symbol indicating that the stora is full.Multi Practical Functions: New design, panel operation with 6 buttons, better peormance. With real-time clock, data stora, data access, alarm, automatic shutdown and other functions.Widely Used: It is suitable for measuring all kinds of telecommunications, electric power, meteorology, machine room, oil field, power distribution lines, tower transmission lines, gas stations, factory grounding network, rob and other grounding resistance.Specifications:Model: ST4100 / ST4800 (Optional)Material: ABSFunction: Grounding resistance test, circuit resistance test, leaka current testEnvironmental Temperature and Humidity: 23 ± 5, lower than 75%RHPower Supply: DC 6V, 4 * 1.5V AA dry battery (not included)Measurement Method: Mutual feeling wayResistance Ran: 0.010-500 (ST4100), 0.010-1200 (ST4800)Resistance Resolution: 0.001Current Ran: 0.00mA-30.0A (ST4800)Current Resolution: 0.01mAClip Size: 55mm x 32mmTime Clock Feature: Have+ ASynchronous Display: + AThe same screen displayDisplay Mode: 4-bit LCD display, black screen designLCD Size: 46mm x 36mmMeasure Time: 1 Time/secondData Stora: 500 groups, the "MEM" stora indication, flashing the "MEM" symbol indicating that the stora is fullData Access: The "MR" symbol indicates when reviewing the dataOvelow Display: OL symbol indication when overran ovelowDisturbed Test: Automatic identify the inteerence signal, indicating the "NOISE" symbol when the inteerence current is highAlarm Function: Send an alarm prompt when the measured value exceeds the alarm set pointCell : Battery power is displayed in real timeAuto Shut Off: It can be set to 5, 10, 15, 20 minutes, OFF, OFF means to cancel the automatic shutdown, the default is 5 minutesPower Dissipation: 115mA MaxWorking Temperature and Humidity: -10~40; lower than 80%RHStora Temperature and Humidity: -20~60; lower than 70%RHInsulation Resistance: 20M above (Between the circuit and the housing 500V)Withstand : AC 3700V/rms (Between the circuit and the housing)<;40A/m<;1V/mPacka List:1 * Earth Resistance Tester1 * Aluminum Case1 * Measuring Ring1 * User Manual (English)
