SECTION 10. PROCESSING INSTRUCTIONS

Example: The 14 coefficients shown below are for Paroscientific "T" Series transducer Serial Number 30135. Your coefficients will be different.

Y1	-3970.348	-3970.3
Y2	-7114.265	-7114.3

C1	70.29398	70.294
C2	6.610141	6.6101
C3	-119.2867	-119.29
* D1	0.0308837	30.884
D2	0.0	0.0
T1	26.33703	26.337
T2	0.8516985	0.85170
T3	21.80118	21.801
T4	0.0	0.0
T5	0.0	0.0

*Y3 and D1 coefficients are entered as Y3/1000 and D1*1000.

The large number of coefficients which must be entered into the program often leads to entry error. As a check on coefficient entry, the third value output by Instruction 64 is the signature of the coefficients. The signature is a calculated number unique to the value and order of the 14 coefficients. For future comparisons, note this signature after entering the coefficients correctly. Signatures will be identical if and only if exactly the same coefficients are entered.

*** 65 BULK LOAD ***

FUNCTION

Instruction 65 inputs given values in up to eight Input Storage locations. Instruction 65 is only in standard PROM OS10-1.1.

The Bulk Load instruction has 9 parameters. The first eight are the values to be entered in input storage locations. The ninth is the input location for the first data value; subsequent data values are placed in sequential input locations.

*** 66 ARCTAN ***

FUNCTION

Calculate the angle in degrees whose tangent is X/Y. The polarity of X and Y must be known to determine the quadrant of the angle, as shown here. If 0 is entered for Parameter 2, the Arctangent of X is the result (limits of ARCTAN(X) are -90°< ARCTAN < 90°).
