c) Maximum Power Rating
The decade has a total maximum power rating of 1 Watt.
 The maximum power rating shall not be exceeded, as damage or even destruction of
the decade may occur.
 Limit applied voltage in relation to maximum activated resistor according to table 1.
 DO NOT APPLY ANY voltage to the decade without activated resistor!
 This may lead to immediate destruction of the decade and in combination with high
voltages even to personal injury!
The maximum operational voltage V
maximum power rating of 1W is calculated in the following way with the maximum
R
activated resistor R
Table 1 shows maximum operational voltage V
resistor R at maximum power rating of 1W:
