Simpson 260 - Ohmmeter Circuit; Zero Ohms Adjust

CPERATING INSTRUCTICNS
If the reference level is QO.DB = .006 watt in
500 ohms, subtract (+)7 DB from the reading to
obtain the absolute value of decibels.
OBMMETER CIRCUIT
When resistances are measured in ohms, the
batteries inside the case furnish power for the
circuit, Since the batteries are subject бо de-
terioration over long periods of time, there is
а compensating circuit in the обшшеђег to make it
possible to extend the useful life of the batter-
ies.

ZERO к ADJUST
Bach tine you use the ohmmeter circuit, check
the zero indication at the right hand end of the ohms
scale before you measure any resistance. Check and
adjust it each time you switch to a different range.
