The MY40 insulation tester is used to measure the Insulation resistance that represents the state of insulation of electric equipment or circuits; It is one of the important measurement parameters in terms of safety and security. The MY40 comes with 4 voltage/resistance ratings on an easy-to-view large display, and incorporates a double-action safety mechanism to keep the user from harm.

Features:

3 1/2-digit LCD;
For each rating, you can save as many as 20 measurements at desired memory address numbers.
Four AA (R6P) batteries the tester retains the measured resistance for approximately 5 seconds after the MEAS switch is turned off.
