The Vanguard Turns Ratio Calibration Standard is designed to calibrate all Vanguard Turns Ratio Testers. It offers selectable turns ratios from 0.8 to 33,000 to 1 with accuracy of ±0.05% of the set value guaranteed for turns ratios from 0.8 to 5,000.
The Vanguard Turns Ratio Calibration Standard features three decade rotary switches (unit, 10th, and 100th) for selecting the turns ratio. A multiplier switch provides ?1, 10, 100, 200, 1000, and 3000 multiplier values.
The unit uses a nickel-iron supper-alloy core toroidal transformer to ensure a very low excitation in order to achieve high turns ratio accuracy. Up to 250Vac test voltage can be used with the Vanguard Turns Ratio Calibration Standard. The high excitation test voltage allows the unit to be used with virtually all turns ratio testers on the market.
A turns ratio calibration certificate is provided with each Turns Ratio Calibration Standard.

Vanguard匝数比校准标准旨在校准所有Vanguard匝数比测试仪。它提供0.8到33,000到1的可选匝数比，精度为设定值的±0.05％，保证匝数比从0.8到5,000。
Vanguard匝数比校准标准具有三十个旋转开关（单位，第10和第100），用于选择匝数比。乘法器开关提供1,10,100,200,1000和3000乘数值。
该装置使用镍铁超合金铁芯环形变压器，以确保极低的激励，以实现高匝数比精度。Vanguard匝数比校准标准可以使用高达250Vac的测试电压。高激励测试电压使该单元可与市场上几乎所有匝数比的测试仪一起使用。
