8. BRAIN TERMINAL BT200 OPERATION
• Example: For the range of 0 to 30 kPa.
A40: INPUT = 30.15 kPa
J15: SPAN ADJ = 0.15 %
Suppose that a standard pressure of 30 kPa is applied and
the value of the parameter of A40: INPUT is 30.15 kPa.
Firstly, obtain the slope error for the span as follows;
Add Ϫ 0.5% to 0.15% of the current value to calculate the
accumulated span adjustment value.
0.15 ϩ ( Ϫ 0.50) = Ϫ 0.35

(18) Test Output Setup (K10: OUTPUT X%)
This feature can be used to output a fixed current from
3.2 mA (–5%) to 21.6 mA (110%) for loop checks.
• Example: Output 12 mA (50%) fixed current.

Press the key twice to
output a fixed current at 50%.
“Active” is displayed while this is
being executed.
Press the (OK) key to cancel
the fixed current output.

IMPORTANT
1. Test output is held for approximately 10
minutes, and then released automatically after
the time has elapsed. Even if the BT200 power
supply is turned off or the communication cable
is disconnected during test output, it is held for
approximately 10 minutes.
2. Press the (OK) key to release test output
immediately.
(19) User Memo Fields (M: MEMO)
This feature provides 5 user memo fields, each holding
up to 8 alphanumeric characters. Up to 5 items such as
inspection date, inspector, and other information can be
saved in these fields.
• Example: Save an inspection date of January
30, 1995.
