Holdpeak_Insulation_Tester (2)The Holdpeak 6688F is designed for testing high current and high voltage electrical systems.  The meter is fairly large and the majority of it is covered with a rubber case.  It features a large back lit LCD display and a rotary dial to change between the different modes.  Included with the tester are a few different style negative probes and a very well insulated positive probe.

Once the batteries are installed the tester is very easy to use.  I do not have another high voltage tester to compare with this one, but all readings were within reason.  The meter is very durable thanks to the rubber casing which also has places to hold the probes.  Overall the tester is made fairly well and is easy to use.
