Performance Characteristics
Introduction
Electrical characteristics in Table 6-1 apply when the 2245A has been cali
brated at an ambient temperature between +20°C and +30°C, has warmed
up at least 20 minutes, and is operating in an ambient temperature between
-10°C and +55°C (unless otherwise noted).
Items listed in the “ Performance Requirements” column are verifiable quali
tative or quantitative limits that define the measurement capabilities of the
instrument.
Environmental Specifications of the 2245A are in Table 6-2, and Mechanical
Specifications are in Table 6-3.
Recommended Calibration Schedule
To ensure accurate measurements, check the performance of this instru
ment every 2000 hours of operation (once each year if used infrequently).
When components are replaced, affected circuits may have to be
readjusted.
