Description

[Pressure Range String]

Pressure Range String

This is the compensated pressure range of the part.

Syntax: [low limit]<sp>”to”<sp>[high limit]<sp>[units}[mode]

Esample: 20 to 32 mmHgA

Where:

Low limit = 20

High limit = 32

Units = mmHg

Mode = A (absolute pressure) (D differential and G gage

pressure also available.)

[Response String]

A Fully Formed Response String

Example:“RL=1E43<sp>0000<cr>

[S/N String]

Serial Number String

YMDD-NN-BSPP (12 character String)

Where:

Y : Year (0~9)

M : Month (A~M, excluding I)

DD: Day of Month

NN: Lot (lot sequence for a given day)

B : Lot Batch# (A~Z)

S : Test Oven Slot# (1~5)

P : Position on Slot (1~15)

Example: 3D23-03-A103

April23,2003

3rd lot of the day

Batch A, Slot 1, Position 03

This allows traceability to original test data

[Temperature Range String]

Temperature Range String

This is the compensated temperature range of the part.

Syntax: [low limit]<sp>[high limit]<sp>”C”

Example: -20 to 85 C

-40 to 125 C and custom ranges also available.

Error Codes

The error codes are bits packed within a double byte.

The four character string is an ascii hex expression.

The error code bits are:

Bit 0 : Part not factory compensated

Bit 1 : Tdex Overflow

Bit 2 : Tdex Over-range

Bit 3 : Pdex Overflow

Bit 4 : Pdex Over-range

Bit 5 : PWL Overflow

Bit 6 : Scale Overflow

Bit 7 : High Resolution Overflow

Bit 8 : Pressure Output Limited to Specific Value

Bits 9 through 15 : Reserved

Example:0100

Represents erro bit 8 set and the Pressure Output Limited

Notes:

Bit 0 : This should not appear if the part has been calibrated

Bits 1 thru 7 : indicate computational error when compensated

Bit 8: indicates that the pressure applied to the part exceeds the

range of the part and is limit to either the high or low limit

{null}

Null Response

No response from the part. In the event of a serial number

mismatch the part will not respond (to avoid buss contention.)
