Very good robust meter until the fuse goes

Have been using these meters for a few weeks now and found them to be very robust and well built. Only have one issue and reason for marking them down is that changing the fuse this takes 2-3 times longer than the old type 318 DMM we where using before. Not a problem for someone that knows what their doing but in a class of new students can guarantee someone will blow the fuses when first using a DMM.

Having now had chance to put this meter through it's paces, what a great purchase I have made! This meter is simple to use and has ranges to suit both home and semi pro use. As described it features many measurement capabilities including all normal requirements plus temperature, frequency and continuity, a very easy to read LCD screen and has a protective case. This meter sells at a very good price and is most definitely excellent value for money.

Decent tool, good instructions

Received the meter last week, slightly bigger than I was expecting, with battery and leads. After using it on a couple of small jobs it works well, clear instructions and the tips of the two probes have covers to prevent accidental contact and to keep clean when not in use.
