FERVE F-1860 
 

WARNING 

  Engines produce carbon monoxide which is odourless, causes slower 

reaction time, and can lead to serious injury through inhalation. Keep service 
areas 

WELL VENTILATED

 while the engine is running! 

  Activate the handbrake and block the wheels before testing or repairing the 

vehicle. It is especially important to block the wheels on front-drive vehicles, 
as the handbrake does not lock the drive wheels. 

  Wear an eye shield when testing or repairing vehicles. Exceeding the limits 

of the F-1860 is dangerous. It will expose you to serious or possibly fatal 
injury. Carefully read and take heed of the precautions described in this 
instruction manual, and make sure that the established limits of the F-1860 
are never exceeded. 

  Under absolutely no circumstances must voltage exceed 1000 VDC or 750 

VDC between any terminal or ground. 

  Extreme caution must be exercised when measuring voltage above 25 VAC 

or VDC. 

  Circuits to be tested must be protected by a 20A fuse or circuit breaker. 

  Do not use the F-1860 if it has been damaged. 

  Do not use the test leads if the insulation is damaged or the cable is 

exposed. 

  Use adequate current clamps when measuring circuits in excess of 10A. 

  To avoid electrical shock, never touch the test leads, tips or circuit while 

testing. 

  Do not make a voltage measurement with the test leads in the 20A or mA 

terminal. 

  When testing for voltage or current, make sure that the corresponding 

function of the F-1860 is the correct one. We recommend you take a test 
reading of a known voltage or current before carrying out a specific function. 

  Choose the proper range and function for the measurement. Do not try to 

take voltage or current measurements that may exceed the ratings marked 
on the function /range switch or terminal. 

  When measuring current, connect the F-1860 in series with the load. 

  Never connect more than one set of leads to the F-1860. 

  Disconnect the live test lead before disconnecting the common test lead 

(COM). 

  The mA and 20A terminals are protected by fuses. In order to avoid possible 

injury or damage, use only in circuits not exceeding 400mA, 10A continuous 
or 20A for a maximum15 seconds. 

 
 

IMPORTANT 

 

  In order to maintain the accuracy of the F-1860, replace the battery as soon 

as the battery symbol appears on the display. 

  Avoid measuring errors from external interference: keep the F-1860 away 

from spark plug cables or wire coils.
