Why are the Thermocouple Codes Shown on the Type 2553 DC Voltage/Current Standard Different From the Service Manual?
Resources:
Solution:
The specifications for the Type 2553 DC Voltage/Current Standard was changed on June 1982. The service manual was not rewritten to reflect these changes. There are two types of 2553:
1979/4 -- 1982/5
2553-00 without GPIB
2553-01 with GPIB
JIS C 1602-1974
Front Panel: PR, CA, CRC, IC, CC
1982/6 -- 1996/8
2553-41 without GPIB
2553-41 with GPIB
JIS C 1602-1981
Front Panel: R,K,E,J,T
The JIS standards related to thermocouples was revised and conformed to the international IEC 584 standard. PR and R are different standards and therefore not included in the list of changes below.
-
K = CA
-
E = CRC
-
J = IC
-
T = CC
