Giới thiệu đồng hồ vạn năng để bàn Keithley 2700

‎Mỗi hệ thống Series 2700 kết hợp đo lường chính xác, chuyển đổi và điều khiển trong một vỏ bọc tích hợp chặt chẽ cho các ứng dụng gắn giá đỡ hoặc băng ghế dự bị. Model 2750 cung cấp khả năng đo ohms thấp mở rộng và hỗ trợ tối đa 5 thẻ Switch 7700 cho tối đa 200, 2 cực multiplexed kênh. Nó cũng chứa một kẹp 20mV tích hợp giúp bảo vệ các thiết bị nhạy cảm khỏi bị hư hỏng và ngăn ngừa lỗi tự sưởi ấm trong quá trình thử nghiệm mạch khô. Chuyển đổi tùy chọn thẻ bao gồm từ các mô-đun multiplexer truyền thống để tự động bù CJC để đo nhiệt độ và hơn thế nữa.‎
