 Reversely concluded all activated resistors from 100kΩ upwards are protected from
overloading up to the maximum decade voltage of 250 VAC rms / DC.
e) Conformity

The appliance t Mi i-Decade R1-3000 o for s to the urre t ersio of IEC 61010-
1:2010 (3rd Edition) + Cor.: 2011 und IEC 61010-2-030: 2010 (1st Edition) at date of
print.
5. Maintenance
 If you have any further technical questions, please directly contact the
manufacturer under:
www.cosinus.de
office@cosinus.de
a) Fault Diagnostics
 If any disturbance occurs, first check the fuse for its function. In case of a triggered
fuse, ha ge it a ordi g to the pre ious haper
 If the problem persists or the cause does not refer to the fuse, stop using the
decade und contact the manufacturer, e.g. under office@cosinus.de.
b) Calibrating
Factory-provided every decade has been calibrated to ensure accuracy according to
te h i al data i the appe di .
 Over the years the resistor values may show higher deviation.
 If you wish a re-calibration, please contact the manufacturer.
c) Cleaning
After disconnecting ALL connection cables every person may clean the decade with a
moist (not wet!) cleaning tissue under application of a mild (not aggressive!) cleanser.
 Take care that no liquids get into the decade.
