Handheld Digital Insulation Resistance Tester is featured with a big digital and bar graph LCD display having back light that enables easy observation. Our Handheld Digital Insulation Resistance Tester is useful when working in dark places. Handheld Digital Insulation Resistance Tester is a hand-free and continuous measurement system with custom made switch. It features a safe design with in-built automatic discharging function for any capacitors present in the circuit.The voltage in the circuit or capacitor can be checked by warning lamp for safe insulation measurements. Handheld Digital Insulation Resistance Tester features data hold and auto power off function. It is available in compact, lightweight, and heavy duty rugged case.
|3 1/2-digit LCD; 4000 count; backlight-illuminated; logarithmic bar graph; extension bar graph-no fluctuations, as the display shows the digits of a reading in the order in which each digit settles.
|The MY40 alerts you by turning on the LOW symbol and sounding the buzzer if the measured value is smaller than the reference value. You can allocate as many as three user-defined reference values to each rating. The factory-set defaults are 0.1 MΩ, 0.2 MΩ and 0.4 MΩ.
|For each rating, you can save as many as 20 measurements at desired memory address numbers.
|Automatic Discharge Function
|The MY40 automatically begins discharge when you turn off the MEAS switch. You can monitor the state of discharge by checking the bar graph and make sure discharge is complete by checking that the segment bar disappear.
|The high-voltage symbol and LED lamp come on to alert you when the MY40 is in insulation testing mode or if any voltage remains to be discharged.
|If you apply an AC voltage of approximately 40 V or higher across the input terminals, the MY40 alerts you by blinking the LED lamp and sounding the buzzer.
|Overrange Input Alarm
|If the voltage being measured exceeds 600 V during AC voltage measurement, the MY40 alerts you by flashing the Maximum Value indicator and sounding the buzzer.
|The tester retains the measured resistance for approximately 5 seconds after the MEAS switch is turned off.
|Four AA (R6P) batteries
|Ambient Temperature/Humidity Ranges
|23 ±5 /45-75% RH
