Product Description Product Description:A resistance meter is an electrical instrument that measures the resistance value of a resistor and is used in parallel with the resistor terminals. The larger the resistance value of a fixed-value resistor, the larger its range. The range is generally zero to several hundred ohms or infinity. Its scale is not uniform.Product Parameters: characterizationMultiple selection of input type/display range and output signal can be adjusted without switching error.AccuracyAnalog (analog) ±0.15%FS +1C (41/2 digits)Display RangeHigh brightness red LED: 0.8" 4-digit 0~9999 Counts.Cold point compensation<=0.3°C/°C. Within 0~40°C.Cord breakage protection functionWhen detecting a broken wire, the display will show OPEN.Linearity correctionDigital linear correction, with digital °C/°F switching function.Input and output protectionInput/output, open or short circuit without damage.Response speed<=1secZero AdjustmentBuilt-in, with zero offset function.Analog output capabilityCurrent output:<=500Ω at 20mA output, Voltage output:10mA Maximum.Digital output characteristicsAdopt RS-485 output, transmission speed 1200,2400,4800,9600,19200,38400Baud Rate can be selected by yourself.Setting functionAlarm contact setting: Hi or Lo can be selected by yourself, and each group of alarm contacts will have an LED light when it is in action.Setting range-19999~19999 Counts adjustable.Inoperative band0~9999 Counts adjustable.Delay time0~99 seconds adjustable.Contact capacitySPDT AC 120V 5A,250V 3A DC24V 3A.4 Set and 5 Set 120V 3A, 250V 3A, DC24V 3A.Voltage resistanceAC 2kV / 1 minute between input/power supply/enclosure, AC 1.6KV/1 minute between input/output/power supply/enclosure.Long-term stabilityAnnual drift<=0.2%.Temperature Coefficient<=80ppm/°CFrom0~60°C;<=50ppm/25°C at 5°C.Environment-10°C~+65°C 20~90% RH without condensation.Storage conditions-20°C~+75°C 20~90% RH without condensation.Power supplyAC/DC85~265V, 7VA.
