After calibrating your 4077's "LIVE" INPUT channel (No. 1), you should

set the high and low endpoints for the BARGRAPH display of Channel

5 ("LIVE" INPUT WITH TARE), using the procedure given below. This

same procedure may be used to scale the bargraph display of any of

the other 4077 data channels listed in Section 1.d. For the relation of

the endpoint values to the other four limit-zone-defining parameters,

see Fig. 8 in the next section.

1. Display Channel 5 (see Section 2.d).

2. Following the general procedure explained in Section 1.f, enter

"SETUP" mode and step to the "LEP" (LOW ENDPOINT)

parameter.

The initial "LEP" setting for Channel 5 is normally "-20000." THIS

WILL HAVE BEEN AUTOMATICALLY SCALED, HOWEVER, SO

THAT ITS DECIMAL-POINT LOCATION MATCHES THAT OF THE

SCALING FACTOR ("F1") YOU ENTERED WHEN YOU CALI-

BRATED CHANNEL 1 IN SECTION 2.e. If, for example, your "F1"

value for Channel 1 was "XXX.X" (where "X" is any number), the

displayed "LEP" value for Channel 5 will be "-200.0." The

decimal-point position will always be the same for all six limit-zone

parameters ("LEP," "LLL," "LOL," "HIL," "HHL," and "HEP").

As mentioned in Section 1.f,

this position cannot be changed

, since

it depends directly on the precision of the last "F1" entry.

3. Using the "ARROW" buttons as explained in Section 1.f, enter the

desired LOW ENDPOINT value for the bargraph display of

Channel 5, as expressed in the engineering units selected for that

channel.

4. Press the STEP button five times. The "HEP" parameter should

now be displayed. Enter the desired HIGH ENDPOINT value for

the bargraph display of Channel 5 (again, as expressed in the

engineering units selected for that channel). The initial "HEP"

setting for Channel 5 is normally "20000."

The "LEP" and "HEP" values for a given channel may be any numeric

constants from -32768 through 32767, provided that the "LEP" value is

less than the "HEP" value. At least 51 units (absolute count) must

separate the HEP and LEP values.
