AC bridge operating frequency is limited to within the range of 20Hz to 100kHz, the working voltage is less than 500V, accuracy range of 0. 001 and below. This procedure does not apply to high-voltage bridge, verification LCR impedance meter and automatic balancing of the bridge.

Standard lamp type evaluation, the requirements for performance measurement can be implemented by reference.2 CitationsGB 15039-1994 "luminous intensity and luminous flux standard lamp" GB 15040-1994 "ordinary photometric standard bulb" JJG 213-2003 "distribution (color) temperature standard lamp test procedures" JJF1002-1998 "national verification procedures to write rules" JJF1059-1999 "Evaluation and Expression of Uncertainty in Measurement" When using this procedure, it should pay attention to using the currently valid version of the documents cited.3 OverviewTotal luminous flux standard lamp is used to maintain and the total flux transfer unit --- lumens (lm) magnitude measuring instruments, is Measure the total luminous flux measuring light relative method. It is the light emission characteristics according to the specific requirements of the production of stable incandescent.4 metering performance requirementsStability 4.1 total luminous flux standard lamp The first submission of the DC power supply standard lamp aging must be in accordance with relevant regulations. Stability after aging should be achieved in the reference Current test ignite under 8h, lamp terminal voltage variation is less than 0.05% (for vacuum lamp) and 0.07% (for inflatable lamp) (Experimental Method see Appendix B). For standard AC-powered lamp, its stability should meet the requirements of GB 15040-1994's. Grading 4.2 total luminous flux standard lamp First standard lamp censorship not rated. When retested after one year, according to the time rate of change of the lamp and the calibration used On one level to be rated according to criteria specified in Table 1. Table 1 standard lamp classification regulations Q is the rate of change in the level of the higher standard inspection standard lamp luminous flux level Working Standard reference or sub-reference is not more than 0.6% Not less than a reference work not more than 0.8% Two of not less than a 1.0% or less Q = | Φ2-Φ1 | Φ1 × 100% (1) Where. Φ1 --- First check the total luminous flux values; The total flux value Φ2 --- retest. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJG 247-2008_English be delivered?Answer: Upon your order, we will start to translate JJG 247-2008_English as soon as possible, and keep you informed of the progress.
