Terminal is dirty inside and unit thinks that leads are connected to mA terminals and knob is at Volts,

Use compressed air to clean terminals and if that does not help use cotton bud with little alcohol on it to clean terminals inside. It will fix the problem.

I purchased the velleman DVM850BL to check current drain from my vehicles batteries as I keep having to recharge my batteries pretty often. Since I am not an electrician or electronic tech, I would just...


To check the current, you'll have to set up your equipment to the mA (milliamp) position. It's located on the right side of the equipment, on the "A" section. The test leads should be positioned accordingly and it is: black in the middle connector (common) and red on the right connector (mA).
It's safe to start measuring the current in a higher scale. Safe for the equipment. So start measuring with the equipment set to the 10A scale and the red test lead on the left connector (which reads 10ADC or so) and check the reading to see if it's below 0.2A, which is the same equivalent of 200mA. If it is, then it is safe to start reading the milliamp (mA). Undo the leads to the mA port and change the equipment scale to 200mA. If you don't observe this and you try read a current higher than 200mA, your equipment might burnout.
But wait: to measure current, you have to open up the circuit that you pretend to do the reading. You can only measure voltage (not current) with the circuit "closed" (also be careful to not try to measure voltage while the equipment is set to measure Amps. Leads will meltdown!!).
To do this, remove one of the batteries terminal. Doesn't matter if it is positive or negative. Then, with the equipment already set to the scale you want, connect one lead to the terminal and the other to the cable or wire that you just disconnected. This will provide continuance of the circuit, having the current going through the DVM and displaying the actual current through that circuit.

Try using compressed air to clean terminal block plugs (specially mA plug) - something is stuck there and unit thinks that you have your leads connected to mA and setting and will beep if you turn knob to any other function.

Why always display ''lead '' fluke 88v


Fluke 88 V displays "LEADS" warning if test leads are in A or mA/uA terminals but switch position does not corespond with those terminals.

Remove all leads and if you still get "LEADS" warning try cleaning all terminals with air. Sometimes dirt gets in A terminals and unit thinks that leads are connected.

Use compressed air or airduster to blow dust from all terminals and hopefully that will fix the problem.

My playstaion 3 wont funell any picture through the av scart lead or the hdmi lead but it still turns on and is running fine ?


Please try the following steps :

Connect your PS3 up as normal, A/V or HDMI, it does not matter.

Turn the PS3 off into standby mode (red light on)

Press and hold the power button. It will beep when you first press it, then beep again 5 seconds later. Release the power button after you hear the second beep.

Wait for the PS3 display to be reset.

You can use this method when you change from A/V or HDMI, it simply resets the display back to standard definition

Hope this helps
