Calibration
Initial calibration consists of two parts, the belt speed calibration and the mass density calibration.
The belt speed calibration correlates the speed signal to the rate the material is moving. For weigh scale
using an encoder or tachometer this is achieved by stopping the belt and calibrating the minimum speed and
running the belt at full speed and calibrating the maximum. (If the weigh scale uses line down contact,
calibration requires only entering the belt speed through the keypad, no calibration is required.)
Speed Low and High Calibration
Low Speed Reference
PROCEDURE:
For weigh scales using tachometer or encoder for speed. If speed input is a signal from a line down
contact, see Speed Calibration using Line down Contact.
The belt must be stopped or running at the lowest speed during the Low Speed Reference.
Using the Ronan local display or HART communicator find the Main Menu;
Scroll down until you reach and highlight Calibration.
Access Calibration by pressing the right arrow key.
Scroll down until you reach and highlight Cal Speed.
Access the Cal Speed by pressing the right arrow key.
Scroll down until you reach and highlight Low Reference.
Access the Low Reference by pressing the right arrow key.
Access the Low Speed Cal by pressing the right arrow key.
Press the F4 key (OK) to the prompt ‘Warning – Remove loop from automatic control
before doing the reference procedure’.
Wait until the prompt changes from
‘Performing Calibrate procedure’ … to ‘Low speed calibrate SUCCESS. Remember to enter
speed’.
Press the F4 key (OK).
Scroll down until you reach and highlight Low Speed 0.0000 ft/min. (Note 0.000 ft/min value and units may
very depending on the what value and units were selected.) (Note: You must access the Low Speed and
either change or acknowledge the value to complete the reference.)
Access Low Speed 0.0000 ft/min by pressing the right arrow key.
Use the arrow keys to select and change the display value to the correct speed. Once the displayed value is
correct, press the F4 key (Enter). ). The Low Speed Reference is complete.
You must proceed to High Speed Calibration to complete the calibration.
