If you select current measuring (A or mA) and have the test lead connected to V then you get this alarm. Same thing if you select Voltage measuring and the lead is connected to a current terminal.
Check the connections and the selector setting.

SOURCE: 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.

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.

Fluke 87

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.

No beep on continuity mod

Needs new buzzer disc, or maybe buzzer disc fell out of its place and just repositioning it fixes the problem - this is the likely cause of your problem.Contact local Fluke authorised service centre or Fluke directly if you are in US and ask them for Audio Transducer (Part Number: 2041050). it should not be more than couple of dollars.
