XPX116 Dual channel current calibratorDetailed product description：

The XPX116 on-site DC current verification signal generator is a handheld instrument that can measure and generate 0-24mA DC current signals. The instrument is equipped with a 4 1/2 LCD display with a display accuracy of 0.1%. The instrument is compact in size, easy to carry, and comes with a built-in battery that can be recharged repeatedly. It is particularly suitable for the calibration, testing, and maintenance of two-wire 4-20mA instruments and control systems.  

Usage conditions
Environmental temperature: 0-+50 ℃
Relative humidity of the environment: below 85%
Power supply: (DC) 9.6-12V

Basic error of XPX116 dual channel current calibrator

Test current range	Output current range	basic error
0-24mA （-25%—+125%）	Fixed range: 4mA (0%) 20mA（100%）	0.1% FS ± 1 word
	Continuous range: 0-24mA （-20%—+125%）

load capacity
When powered externally, the maximum DC supply voltage is 45V; when powered by an internal battery, the maximum load of 20mA is 750 Ω.  

Low voltage display of power supply
Under internal power supply, when the load is 100 Ω and the output current is 26mA, the LCD displays "LOW BATTERY", and the power supply voltage is between 9.55V and 9.2V.  

temperature effect
When the ambient temperature of the product deviates from the reference conditions by 20 ± 2 ℃, the temperature effect is 0.2% FS/10 ℃.  

display
4 1/2 LCD display with a resolution of 0.01mA or 0.01%.
