td1510 high-precision dc calibrator
暂无内容


overview

model td1510, a wide-range, high-precision and multi-function calibrator with a built-in dc standard source. the apparatus can accurately outputs dc voltage, current, power and electrical energy with the optional accuracy classes are 0.01, 0.02 and 0.05. applied to calibrate various types of dc electric measuring instruments.

features

dc electrical parameters output: voltage is up to 1150 v, current is up to 120 a, the low-current is as low as 0.1 μa.

● value output mode: standard source and output source modes, easy to calibrate both digital meters and analogue meters.

● value adjustment method: fixed-point, rotary encoder, step and potentiometer (option).

● output switch: the output can be turned on/off arbitrarily by one-touch operation.

● statistics and analysis of data: calculate the maximum, minimum, average and standard deviation, and then analyze the stability and trends. 

● excellent human-computer interaction: large lcd touch screen display, touch and button operation modes, easy for users to measure manually.

● electric energy meter calibration: built-in a dc low-voltage standard source with an output range of ±(10 μv to 4.4 v), and standard pulse i/o interfaces to calibrate electrical energy meters by direct access or indirect access.

● transmitter measurement (option): measure the secondary dc signal of the transmitters.

● proprietary software (option): support the calibration of the checked meters by semi-automatic or full-automatic, data management and report export.
