Entering Error Limits

The Error Limits option enables you to set limits for an incoming
signal. When the signal falls outside the programmed limits, an error
indication appears on the display screen. To set error limits, follow
the steps below.

Note:

If you are in the PROG menu, proceed directly to Step 4. If
you scroll to a different option, press [ENT] twice to select
that option (once to enter and again to confirm the selection).

1.

Press [ESC]. The UTX878 enters the

User Program

.

2.

Press the [

X

] key until

PROG

is bracketed in the upper left corner

and press [ENT].

3.

Use the [

S

] and [

T

] keys to scroll to the desired

Channel

and

press [ENT].

4.

Scroll to the

Error Limits

option and press [ENT].

5.

The first prompt asks for the

Minimum Signal

limit for the

transducer signal received by the UTX878. The E1:LOW
SIGNAL error message appears if the signal strength falls below
the limit programmed here. Press [ENT]. Use the arrow keys to
change the value and press [ENT].

6.

Repeat the steps above for the

Maximum Signal

limit.

7.

The next prompt calls for the

Minimum Velocity

limit. Press

[ENT]. Use the arrow keys to change the value and press [ENT].

8.

Repeat the steps above to change the

Maximum Velocity

limit.

(The E3: VELOCITY RANGE error message appears if the
velocity falls outside the minimum and maximum limits.)

9.

The meter now asks for the

Min Amplitude,

the lower limit for the

amplitude discriminator. The discriminator measures the size of
the transducer signal sent from the UTX878. If the signal falls
outside these limits, the E5: AMPLITUDE error message appears.
Press [ENT]. Use the arrow keys to change the value and press
[ENT].

10.

Repeat these steps for the

Max Amplitude

, the upper limit for the

discriminator.

11.

The next prompt asks for the acceptable limits for the sound
speed, based on conditions in your particular system. The E2:
SOUND SPEED error message appears if the fluid sound speed
exceeds that entered in the Fluid submenu by more than this
percentage. Press [ENT]. Use the arrow keys to change the
percentage and press [ENT].
