DISPLAY
The M351 displays alpha-numeric data, but due to the nature of 7-segment
LEDs and the limitation of six digits, some information is abbreviated.
All segments and annunciators are illuminated for a brief display test upon
power up. The current gross weight is then displayed in default units.
LED DISPLAY
The LED display is a six digit, 7-segment bright red LED screen with
9 annunciators to show weight and status information. The – (Low
Limit) = Yellow, + (High Limit) = Red and OK (Within tolerance) =
Green. Also there are annunciators for 5 units of measure.
Figure 1: Model 351 LED Display
ANNUNCIATORS
Annunciators provide mode and status information. When illuminated, they
indicate the following conditions:
-(Yellow) Current weight is under the low limit tolerance.
OK (Green) Current weight is within tolerance.
+(Red) Current weight is over the high limit tolerance.
ÚÚ 0ÙÙ Displayed weight is at center-of-zero (±¼ display
graduation).
~Scale is in motion. Motion inhibited transmits will be delayed
until motion ceases.
lb The displayed value is represented in pounds.
oz The displayed value is represented in ounces
