Pewter - Well switched mine on, put croc's together base jaw to base jaw, null leads <0.00 flashing, part croc's and then rejoin base to base <0,00 flashing, beeos and latches, move leads left and right makes no difference still reads <0.00, part jaws rejoin straight <0.00 beeps and latches.
How do actually get a reading if you have nulled the leads ?
Do you switch off after every test, to clear the memory.
If its flashing its less then 0 <0.00
example:
-if measure leads and its 0.16, press the test to null them to get zero.
-If you touch them together again and get flashing <0.00 its less then 0.
-If you un null the leads and measure them you will find lead is now measuring less 0.14 for example.
thats a problem as all results would be -0.02.
I only get a reading when the leads complete a circuit and measure the resistance of something or just the leads.
What i have done to test the problem is connect the 2 leads together as if to null them.
I usually get around 0.14.
By moving the actual lead around which causes the plug to move, it then increases in resistance.
So i can connect (or could) connect the 2 leads together get a reading of 0.22, move the plug and get anything from 0.1-1.1
I could null leads, then crouch down to measure R1+R2 on a socket, recheck the leads and they have gained resistance, affecting the result.
This company have had a few problems with this, i was told.
I always switch the machine off after use (unless i forget)
Since i had the problem the first time i always check they say 0 (not <0.00 ) before and after measuring resistance on everything. This way i am checking the reading is true not affected by a change in resistance of the leads.
Im glad i made the video this morning to prove what it was doing, as its now working fine almost ( i only see a change of 0.01 if i really rotate the plug)
I wonder if they fitted new sockets and there's a little manufacturer protective film of grease that needs wearing off?
I was told they fitted new sockets this time.
