Product Description
The 3250/3252/3302 transformer test instrument is a precision test system, designed for transformer production line or incoming/outgoing inspection in quality control process, with high stability and high reliability. With the enhanced capability in turn ratio measurement, they can solve the measuring problems of low coupling coefficient, transformer's turn ratio and turn number with more precise measurement. In addition to transformer scanning test function, the 3302/3252 have LCR Meter function. Operator-friendly and value-added, they can help you reduce production cost greatly.
Feature:
1. Test frequency: 20Hz-200KHz/1MHz, 0.02% accuracy.
2. Basic accuracy: 0.1%
3. Output impedance modes, measurement results are compatible with other well-known LCR meters.
4. Enhanced Turn Ratio measurement accuracy for low permeability core
5. Fast Inductance/Turn Ratio measurement speed up to 80 meas. /sec
6. Fast DCR measurement speed up to 50 meas. /sec
7. Bias current source directly control capability (3252/3302)
8. 320x240 DOT-matrix LCD display
9. Support versatile standard and custom-design test jigs
10. Four-terminal test for accurate, stable DCR, inductance and turn ratio measurements
11. Build-in comparator; 10 bin sorting with counter capability (3252/3302)
12. 2M SRAM memory card, for setup back-up between units
13. Standard RS-232, HANDLER, PRINTER interface
14. 50 internal instrument setups for store/recall capability

3.Quality inspection: All products should be inspected strictly before shipment. Ensure the good function and appearance.
Packaging & Shipping
Package and transport
General package(Paper carton or plastic bag): For small goods, Package it with form and pack paper to guarantee unbroken during the transport.
Wooden case package: For larger scale goods as machine equipment etc, we have special skilled carpenter, who would make the proper wooden case with exact thickness,density,length. The up arrow ↑marked on the outer wooden case. Buffer material would be put in the wooden case to prevent crack and shock. We will inform you the delivery note. You just need to wait for phone call, then pick up the goods at the nearest logistic station .(Please let me know in advance if you want get the goods at home.)
