Measuring Capacitance
• Eight ranges: 1nF, 10nF, 100nF, 1µF, 10µF, 100µF, 1000µF, 10,000µF and autorange
• Measurement Method: Computed from constant current source charge time.
Typical 0.2V - 1.4V AC signal level
• Input Protection: 1000 V (HI terminal)
Measuring Temperature
• -80.0°C to 150.0 °C, -110.0°F to 300.0 °F
• Auto-ranging measurement, no manual range selection
• Measurement Method: 2-wire Ohms measurement of 5 kΩ thermistor sensor
(YSI 44007) with computed conversion
• Input Protection: 1000 V (HI terminal)
