Canberra 9233653E V3.0 Error #338: THE NUMBER OF ITERATIONS FOR ECC INTEGRATION MUST BE GREATER THAN OR EQUAL TO 3.

Genie™ 2000 Spectroscopy Software · taken from the manufacturer’s manual, pages cited

Error code#338

The number of iterations for ECC integration must be at least 3, as it uses iterative Monte Carlo methods that require minimum iterations to converge properly. The manual's first action is: “Also, the maximum number of random points [N] that ISOCs can generate is 2^20. Thus, if random points for the first iteration [n1] is set to a value greater than 2^18, then for the third iteration the number of random points would exceed 2^20, and the above error message would appear. Change the n1 value so that the product 8*n1 product does not exceed 2^20.”

What #338 means

THE NUMBER OF ITERATIONS FOR ECC INTEGRATION MUST BE GREATER THAN OR EQUAL TO 3. p. 418

Common causes

  • The Efficiency Calibration Computation [ECC] process uses an iterative Monte-Carlo numeric integration method that doubles the number of random points at the end of every iteration. The ECC requires at least 3 iterations to estimate the convergence of the efficiency integral. p. 418

What to do

  1. Also, the maximum number of random points [N] that ISOCs can generate is 2^20. Thus, if random points for the first iteration [n1] is set to a value greater than 2^18, then for the third iteration the number of random points would exceed 2^20, and the above error message would appear. Change the n1 value so that the product 8*n1 product does not exceed 2^20. p. 418

Before you service the product, read the safety instructions in the manual p. 526.
