Introduction

This specification based on the national measurement specifications JJF 1071-2010 "National Calibration Specifications writing rules" Program system. And JJF 1001 "common measurement terms and definitions", JJF 1059.1-2012 "Measurement Uncertainty Table Show "together constitute the support of the development of the basic calibration specifications series normative work. This specification is the first release. DC electronic load calibration specification

1 Scope

This instruction applies to DC electronic load calibration, power DC electronic load test system functionality or battery test Calibration test system can also refer to the corresponding items of this specification, this specification does not apply to the exchange of electronic calibration load. 2. References This specification refers to the following documents. JJG315-1983 DC digital voltmeter (Trial) JJG598-1989 DC digital ammeter (Trial) GB/T 13978-2008 DMM GB/T 14714-2008 micro computer system switching power supply for universal norms GB/T 17478-2004 low voltage DC power supply performance characteristics For dated references, only the dated edition applies to this specification; undated reference documents Member, the latest edition (including any amendments) applies to this specification.

3 terminology and units of measurement

The following terms and definitions adapted to this specification. 3.1 DC Electronic Load DCelectronicload Composed by the electronic power device for absorbing the DC power device by another device or system power supply. Note. Most of the DC electronic load can simulate four kinds of consumption pattern of electrical equipment, including the constant current mode, constant voltage mode, Constant resistance mode and constant power mode or program control of the four modes dynamic combination. Most DC Sub load at work can have a voltage measurement, current measurement, power measurement function. 3.2 constant current mode constantcurrentmode (CC) DC electronic load absorbing constant current mode of operation. In this mode, regardless of the input voltage is changed, straight Flow electronic load absorbed by the current setting value of constant current. 3.3 Constant Current Mode Load regulation CCmoderegulation When the input voltage is within the allowable range, constant current DC electronic load set value remains within control limits Ability. 3.4 constant resistance mode constantresistancemode (CR) DC Electronic Load analog resistive mode of operation. In this mode, the current obey Ohm's law with the input Pressure change and change, DC electronic load input port is equivalent to a constant resistance. 3.5 the constant voltage mode constantvoltagemode (CV) DC electronic load absorption constant voltage mode. In this mode, the DC electronic load regulator will absorb Current input port voltage is maintained at a constant voltage setpoint.
