5725A的電壓輸出可在5700A系列校準(zhǔn)器的5725A的電壓輸出可在5700A系列校準(zhǔn)器的前或后結(jié)合柱上使用。這就消除了在需要放大和標(biāo)準(zhǔn)校準(zhǔn)輸出的過程中移動電纜的需要。前或后結(jié)合柱上使用。這就消除了在需要放大和標(biāo)準(zhǔn)校準(zhǔn)輸出的過程中移動電纜的需要。

5725A前端或后面板輸出綁定位置僅用于當(dāng)前輸出。通過它們提供了擴(kuò)展范圍的交流和直流電流。由于大多數(shù)高電流范圍的電表都使用一個(gè)單獨(dú)的高電流輸入端子，這種配置通常不需要在過程中移動電纜。如果需要一個(gè)單點(diǎn)電流輸出，則可以配置5700A系列校正器，通過5725A的綁定位置來輸出所有當(dāng)前輸出。

型號5725A操作功能和范圍:

• 交流電壓:220v至1100 V rms至70 mA (50 mA < 5 kHz)， 40hz至30khz;220至750V rms最高可達(dá)70 mA, 30 kHz至100khz。

• 直流電流:0 A到11 A。

• 交流電:1 A到11 A rms, 40hz到10khz。

The 5725A Amplifier enhances the 5700A Series Multifunction Calibrators in the ac voltage, ac current, and dc current functions. The 5725A operates under complete control of the 5700A Series calibrators through an interface cable supplied with the 5725A.

Enhancements to 5700A/5720A ac voltage output capability provided by the 5725A:

• Frequency limits at higher voltage increase to 100 kHz at 750 V, 30 kHz at 1100 V

• Load limits are to 70 mA for frequencies above 5 kHz, and to 50 mA for frequencies less than 5 kHz

• Capacitive load limits are increased to 1000 pF

Voltage output from the 5725A is available at the 5700A Series Calibrators' front or rear binding posts. This eliminates the need to move cables during a procedure that requires amplified as well as standard calibrator outputs.

The 5725A front or rear panel OUTPUT binding posts are only for current output. Extended-range ac and dc current is supplied through them. Since most meters with a high current range use a separate high current input terminal, this configuration normally eliminates the need to move cables during a procedure. If a single-point current output is needed, the 5700A Series Calibrator can be configured to source all current outputs through the 5725A binding posts.
