This voltage and current source signal generator with a ranges of 0~10V/0-22mA adopts a full digital encoder to adjust the setting. Compared with the traditional resistance adjustment, it avoids the drift problem caused by the deviation of the resistance value over time and temperature. The digital adjustment is more accurate and convenient, and the setting function is richer.Features:Voltage and current regulation, one button switching, independent wiring and simultaneous output.Current output 2, 3, 4-wire system, active full compatibility.Output with short-circuit protections, power non-polar access, with direct current bridges isolation protections.Multiple output ranges: 10V/5V/ 0-10V/2-10V/4.0-5V/0-3.3V/0-2.5V/0-1V/-10V-0V/0-20/0-22/4-20mAMultiple display modes: voltage and current /100.0% percentage /50.0hz, 1-1500.Coarse / fine adjustment dual mode, the number of adjustment turns can be set.The encoder knob has 360 degree stepless adjustment, which is stable. Unlike the adjustable potentiometer, the resistance is easily affected by temperature and humidity. The carbon brush becomes thinner and thinner after long-term use, and the resistance changes.4-digit high brightness nixie tube, 2-digit decimal point high-precision adjustment, output can be calibrated.Specifications:Material: ABS+metalType: standard type, upgrade type (optional)Working voltage: Direct current 24V (allowable ranges: Direct current 15V ~ 30V)Working current: power 1W (non recharging) /5W (reharging)Voltage output: 0-10V adjustableAccuracy; 0.01VMaximum current: 20mACurrent output: 0-22mA adjustableAccuracy: 0.01mA adjustableThe current sampling resistance: 10-500 ohms, which can be short circuitedDigits displayed on the nixie tube: 4, with two decimal placesEncoder knob: 1 turn 20Working temperature: 0~50Working humidity: 0~95% RHStorage temperature: -40~85Battery: 1 * lithium battery, 1600mAh (Only upgrade type)Package size: 150 * 150 * 50mm / 5.9 * 5.9 * 2.0inPackage weight:Standard type: 238g / 8.4ounceUpgrade type: 282g / 9.9ounceNote: Only the Upgrade package version of the signal generator has a built-in battery, but the standard version does not.Standard Type Packing List:1 * Signal Generator (without built-in battery)1 * Set of Test Clip1 * USB CableORUpgrade Type Packing List:1 * Signal Generator (built-in battery)1 * Set of Test Line1 * USB Cable
