- Display:
3 1/2-digit LCD; 4000 count; backlight-illuminated; logarithmicbar graph; extension bar graph-no fluctuations, as the displayshows the digit of a reading in the order in which each digitsettles. - Comparator function:
The MY40 alerts you by turning on the LOW symbol and sounding thebuzzer if the measured value is smaller than reference value. Youcan allocate as many as three user-defined reference values to eachrating. The factory-set defaults are 0.1MΩ, 0.2MΩ, and 0.4MΩ. - Memory function:
For each rating, you can save as many as 20 measurements atdesired memory address numbers. - Automatic discharge function:
The MY40 automatically begins discharge when you turn off the MEANswitch. You can monitor the state of discharge by checking the bargraph and make sure discharge is complete by checking that thesegment bar disappear. - High-voltage indicators:
The high-voltage symbol and LED lamp come on to alert you when theMY40 is in insulation testing mode or if any voltage remains to bedischarged. - Live-line alarm:
If you apply an AC voltage of approximately 40V or higher acrossthe input terminals, the MY40 alerts you by blinking the LED lampand sounding buzzer. - Overrange input alarm:
If the voltage being measured exceeds 600V during AC voltagemeasurement, the MY40 alerts you by flashing the Maximum Valueindicator and sounding the buzzer. - Auto-hold function:
The tester retains the measured resistance for approximately 5seconds after the MEAS switch is turned off. - Dimensions:
125 (W) × 103 (H) × 53 (D) (mm), excluding protrusions - Weight:
420 g (main unit and batteries only, excluding accessories) - Batteries:
Four AA (R6P) batteries
