Rated 5 out of 5 by from Great For Caravan and Car Testing Bought this some time ago and used it mainly for caravan battery capacity testing. Very useful but suggest you remove or isolate the battery if not using for some time as the (slightly non-standard i.e. not AAA) will go flat

Rated 5 out of 5 by from Did the job I bought this to check the circuits in our caravan. It worked fine - but a fuse gripper would have been a useful item to pack with it, I did not want to grub around under the footwell of the car to get one out. I would have preferred to buy just the leads so that I could have connected them to my multimeter but they were out of stock at all local stores and online.

Will the display stay on once it has been switched on, or will it automatically switch off after a while ? I want to be able to leave this in a locked car and look in the window over an extended period to see what current is being drawn.

Asked by: Jams
It displays a result when the button is pressed but this goes off after a short while.

I have just purchased this item , but on opening found that the probe has provision for a blade fuse which was not supplied neither any mention of what amperage fuse to use.

Asked by: Boa0
The probe isn't fused, that is where you place the fuse from slot you are testing. You take the blade fuse out of it's slot and place it into the probe. You plug the probe into the slot the fuse came out of. This then allows you to test the volts/amps draw going through that fuse slot. Please make sure you do not exceed the stated maximum for volts/amps.

A caravan with 80wt solar panel &10amp blade fuse fitted.  Can this 'gadget' be used be used to check the power from Solar Panel OUTPUT as battery struggles winter days to keep alarm & tracker with sufficient power. Trying to check if working properly.

Asked by: Bernard in Tring
Unfortunately we couldn't guarantee this would be suitable as it is not the intended purpose of the unit. If you are just looking to check the output from the solar panel a standard multimeter connected to the battery clips of the panel will allow you to check.

If left plugged into the fuse holder for an extended period of time, will it measure/record the peak draw on that circuit in such a way that makes it possible for you to work out what the peak was without having to sit and watch it?

Asked by: STR675
I am sorry but the item in question does not support use in your intended application.
