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 kW 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 MW 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.

WARNINGS
• If the Resistance decade is used in a manner not speci- fied
in this Users Manual, the protection provided by the
equipment may be impaired!
• Do not use the Resistance decade if any damage is no-ticed!
• If the voltage of circuit connected to the Resistance de-cade
is higher than safety level its metallic enclosure must be
connected to PE (ground) terminal of circuit!
• Do not exceed ratings marked on front plate!
• MA 2115 does not contain any user replaceable compo-nents.
TECHNICAL DATA
Resistance range:
- standard: 0 to 9 999 999 W
- optional on request: 7 decades with possible
extension to 9 x 1 MW and/or 9 x 0.1 W
Accuracy:
- individual decade unit : ± 1% + 0.08 W
- 9 x 0.1 W option: ± 2 % + 0.08 W
- overall: ± 1% + 0.4 W
Maximum ratings:
- continuous power dissipation: 1 W / resistor
- voltage / current: marked on front plate
- working voltage to case: 500 V d.c. / a.c. rms
Dimensions (w × h × d): 267 × 89 × 97 mm
Weight: 0,8 kg
Protection classification: Class I
Over-voltage category: CAT III 300 V
Pollution degree: 2
Working temperature range: (0 to 40) °C
Storage temperature range: -10 °C to 80 °C
Max. humidity: 85 % RH (0 to 40) °C
APPLICATION HINTS
In general always predict and set required value before connection
into circuit and/or turning power on of it to avoid destructive short
circuit currents.
GENERAL
MA 2115 Resistance Decade is intended for all application areas
where variable resistances selected by hand are required. It is
passive electric device housed in metallic case. It consists of 7
decades with each of its setting rotary switch with range multiplier
from 0 to 9, and. Safety F 4 mm sockets are connected to each
resistance chain that it could be individually accessible. It is also
possible to split resistance chain into two or more independent
insulated groups by selection of rotary switch position.
