The Keithley 175 is a 4.5-digit autoranging digital multimeter engineered for benchtop and portable electrical measurement applications. Its backlit LCD display with 0.5-inch character height delivers clear readings across DC and AC voltage, current, resistance, and diode test functions. True RMS measurement capability on AC parameters ensures accuracy across frequency-dependent loads, while independent measurement ranges for each function provide the resolution needed in electronics testing, troubleshooting, and field service environments.
