Appendix A: Specifications
The items listed in the following tables describe the performance of the WFM
601i Serial Digital Component Monitor. Performance Requirements are
generally quantitative and can be tested by the Performance Verification
Procedure, contained in the Service Manual.
Reference information (RI) is valuable data pertaining to the operation and
measurement capabilities of this instrument. Only a few of the items listed in
this category are testable in the Performance Verification Procedure.
Performance Conditions – The Requirements listed in the electrical specification
portion of these specifications apply over an ambient temperature range of 0
°
C
to +40
°
C. The rated accuracies are valid when the instrument is calibrated at an
ambient temperature range of +20
°
C to +30
°
C, after a warm–up time of 20
minutes. Test equipment used to verify Performance Requirements must be
calibrated and working within the limits specified under the Equipment Required
list.
These instruments are intended to operate from an ac power source that will not
apply more than 250 V rms between the supply conductors or either supply
conductor and ground. A protective ground connection by way of the grounding
conductor is essential for safe operation.
Calibration Interval
The recommended calibration interval is 12 months.
Environmental specifications are listed toward the back of the following tables.
In addition a list of appropriate safety and electromagnetic interference (EMI)
standards also can be found there.
