6. Initial calibration 

 

Set up the demo multimeter vertically. 

 

Do  not  connect  measuring  leads  to  begin 
with. 

 

Set the toggle switch 1 to 

.  

 

Set the power switch to  . 

The needle will point to the zero point of the scale 
on the left. If it does not, the amount of charge of 
the battery should be checked. 

7. Operation 

7.1  To switch on: 

 

Set the power switch to  . 

 

7.2  Checking battery charge: 

 

Turn on the demo-multimeter. 

 

Disconnect all measuring leads. 

 

Set the toggle switch 2 to 

 

Set the rotary switch to 

.  

If  the  battery  is  sufficiently  charged,  the  needle 
will  point  to  the  following  range  indication, 

.  If  this  is  not  the  case,  the  battery  will 

need to be replaced immediately. 

 

7.3  Zero point calibration: 

 

Turn on the demo-multimeter. 

 

Turn the rotary switch to 600 V. 

 

Connect the common/ground socket and the 
voltage  measurement  socket  together  by 
means of a short connecting lead. 

 

Turn  the  zero-point  trimmer  screw  to  adjust 
the zero point as needed. 

 

7.4  Zero  point  calibration  for  centre  zero 

point: 

For measurements of DC current and voltage, the 
zero point of the scale can be moved to the centre 
of  the  dial.  For  this  purpose  the  scales  are  la-
belled with red numbers.. 

 

Turn on the demo-multimeter. 

 

Disconnect all measuring leads. 

 

Set the toggle switch 2 to 

 

Set the toggle switch 1 to 

.  

 

Use the zero-point trimmer to line up the nee-
dle precisely in the centre of the dial (red di-
vision). 

 

7.5  To switch off: 

 

Set the power switch to 

 

Set the four-way switch to 

When the meter is turned off, the needle points to 

 

7.6  If a measurement is interrupted by battery 

cut-out: 

After  45  minutes  of  use,  the  multimeter  is  auto-
matically shut off and the needle will then point to 

To switch back on: 

 

Set the power switch of the multimeter to off 
and then use it to turn the meter back on.
