Overload protection	1000V — When the rise time is less than 1ms, the signals center on trigger level. Range Resolution Accuracy 0.01% ±(1.2%rdg + 30dgts)
Overload protection	1000V — Two-channel temperature measurement can be performed via temperature connectors.
Temperature Sensor	Applicable to K type (chromel-silicel) thermocouple. Spare parts are point contact K-type (chromel-silicel) thermocouple (only applicable to the measurement when temperature is below 230°C). Range Accuracy 0.2 °F Resolution ±(2.0%rdg + 30dgts) ±(1.0%rdg + 30dgts) ±(2.5%rdg + 50dgts) 40°C ~ 400°C 400°C ~ 1000°C -40°F ~ 104°F 104°F ~ 752°F 752°F ~ 1832°F 0.1 °C ±(2.5%)
Overload protection	1000V — When the rise time is less than 1ms, the signals center on trigger level. — The pulse width is greater than 2ms for 10Hz to 200kHz. The pulse width depends on signal frequency. Range Resolution Accuracy ±(1.2%rdg + 30dgts)250 mS 0.001mS ~ 0.01mS
Overload protection	1000V RemarkRangeResolution Open-circuit voltage is around 3V; when the buzzer selects short circuit for sound warning, the resolution is less than 10W. The buzzer continuously sounds, the resolution is greater than 50W. The buzzer does not sound. When the buzzer selects open circuit for sound warning, the resolution is greater than 50W. The buzzer continuously sounds, the resolution is less than 10W. The buzzer does not sound. 0.01W
Overload protection	1000V RemarkRangeResolution Open -circuit voltage is around 3V. The forward voltage drop value of the measured PN junction is approximately £ 3V. When the buzzer activates, it will beep briefly for the normal semiconductor junction; if the semiconductor junction shorts out, it will beep continuously. Silicon PN junction drops between 0.5 ~ 0.8V as the normal value. 0.0001V
