2505A use rack mount kit, (Single) P/N 1830-910 – (Dual) P/N 1830-911. The Model 1505A is shipped without any type of rack mounting equipment the new design allows for use as a terminating sensor and its low weight of 544.3 g (1.2 lb) reduces any stress on connectors. - Page 12 Section II – Preparation for Use and Installation Do Not Use in Explosive Environments CAUTION: The 1505A and 2505A are not designed for operation in explosive environments. Do Not Operate Without Covers WARNING: This device should be operated with all panels and covers in place. Operation with missing panels or covers could result in personal injury.

Page 13: Principles Of Operation
Theory of RF Measurements with the 2505A and 1505A Power Measurements RF power is measured in terms of a power change across the precision resistance leg of a TEGAM 1830A, 1806A, 1806 Bridge Circuit. A digital voltmeter measures voltage across the precision resistance leg which can be used to determine the power. -

TEGAM Model 1830A, 1806A, and 1806. The bridge operates on the principal of DC substitution, so only DC voltages and currents are present at these terminals when connected. In addition, the TEGAM Model 1805B can be used to heat the 2505A and 1505A with cable CA- 29-48. - Page 16 TEGAM Model 1830A, 1806A, and 1806.

Page 17: Calculating Calibration Factors
Calibration factor of the Feed-through Mount When connecting a 1505A or 2505A to an 1806 or 1806A; in addition to a 2 hour warm up time, operator should observe stability in the bias voltage. Bias voltage stability refers to less than 50uV change per 30 minutes as a general guideline. The error light does not apply when connecting the 1505A or 2505A to the 1806A. - Page 18 Start with the signal flow diagram. In this case, a Generator “g” is represented by an ideal source “s”, and its port reflection, and the sensor is termed the load, “l”. 10 TEGAM WAY • GENEVA, OHIO 44041 440-466-6100 • FAX 440-466-6110 • www.tegam.com...

Page 23: Maintenance And Servicing
Maintenance Calibration of 1505A/2505A The 1505A & 2505A should be calibrated periodically to maintain accuracy when using these standards. The frequency and method of calibration can vary based on the customer’s requirement. TEGAM maintains full capability to calibrate these standards. Contact TEGAM to discuss your specific needs or to set up a return RMA to have your standard calibrated. - Page 24 Do not snap the wrench more than once as this also causes over-torque.
