Used KEITHLEY 238 #9021108 for sale

KEITHLEY 238 is an automated electronic test instrument designed for high-precision voltage and current measurements. It features a measurement range of up to 100V/20mA and can measure both DC and AC signals with high accuracy. Its main purpose is for high-accuracy measurements of voltage, current, and resistance. 238 has multiple measurement modes including DC volts, DC current, 2-wire resistance, four-wire resistance, and many others. Its display is an LCD screen with 128 x 64 pixel resolution for easy data visualization. Furthermore, it can be interfaced with other computers, instruments, and digital data processes using a GPIB or USB interface. KEITHLEY 238 is equipped with an over-voltage and over-current protection to ensure the safety and accuracy of measurements. It is also temperature-compensated to lock in accuracy and make accurate readings from 5°C below to 45°C above the set temperature. In addition, it is highly resistant to magnetic fields and EMI which makes it an ideal choice for use in reliable and safety testing of electronic components. For further testing and data collection purposes, 238 has a programmable memory, which can store up to 15M digital or analog readings. It also has comprehensive mathematics functions, such as integration, differentiation, and other integral functions for statistical data processing. It also provides functions for limit-testing to alert the user when a reading is out of set tolerances. KEITHLEY 238 is equipped with a high stability internal reference and current source for very fine and accurate readings. Additionally, its high-accuracy, reasonable speed, and precision makes it suitable for use in applications such as ICs, transistors, power systems, and other precision testing. Finally, it has low operational noise and low thermal error to further increase its accuracy.
