Single resistor application 

Desired value has to be set by rotating 

the appropriate knobs of rotary switches. Each knob contain 
multiplier dial of marked range. 

Example:

 to set resistance of 2850 k

W

 select 2 x 1M, 

8 x 100k, 5 x 10k and rest to 0. Banana plugs must be connected 
into sockets that cover at least all positions different to 0.

Split chains 

If e.g. knob x 1k selects position

the MA 2115 is split 

into high resistance decade part in range (0 – 9990 k)

 

W

 

and low 

resistance decade part in range (0 – 999)

 

W

Use appropriate 

sockets.

Voltage divider 

Simple voltage divider can also be configured for 

test purpose. Example: voltage divider with 1000:1 ratio and input 
resistance of 2 M

W

 has to be realized. Set 2 x 1M, 2 x 1k and rest to 

0. Input voltage is connected between most left sockets and socket 
in bottom right corner and for output voltage use socket between x 
10 k and x 1 k and the same socket on right corner. If voltage 
connected to divider is higher than 50 V connect PE into green 
socket.

MAINTENANCE
Inspection 

To maintain operator safety and ensure reliability of MA 

2115 it is good practice to inspect it on a regular basis. Check that the 
enclosure is without defects such as scratches or breaks. If any defect 
is found please consult repair centre, distributor and/or manufacturer.

Cleaning 

Use a soft cloth slightly moistened with soapy water or 

spirit to clean the surface of the instrument and leave the instrument 
to dry totally before using it. 

Notes!
• Do not use liquids based on petrol or hydrocarbons!
• Do not spill cleaning liquid over the instrument!
Calibration 

It is essential, that MA  2115 be regularly calibrated. We 

recommend an annual calibration.

Service 

Repairs under or out of warranty time: Please contact your 

distributor for further information.
