4215-HS Indicator

Manual

(PM-4101)

The following procedure should be followed to calibrate the Model 4215-HS itself. This calibration requires

the use of a precision millivolt per volt reference which will be attached on the load cell connector. The

resulting scale factors are recorded in the non-volatile memory of the Model 4215-HS.

ATTENTION: System Calibration should ONLY be performed by trained, QUALIFIED TECHNICIANS utilizing the

proper precision devices to ensure the most accurate performance of the unit.

1. To enter system calibration mode, turn off the Model 4215-HS. Hold down the two end buttons ( “<“ and “>“

) while turning power back on. As soon as the display comes on you can release the buttons.

2. The unit will go through its regular start up sequence but rather than entering run mode and showing

the load in pounds a password prompt will be displayed. Enter the number 777 as the system calibration

password.

3. The unit will now display “Unit mV / V Cal” to indicate that it is ready to be calibrated. A five minute warm-

up period with the millivolt-per-volt reference attached is recommended at this time if the unit has just been

turned on or the millivolt-per-volt reference has just been attached. Press any button to clear this display.

4. You are now prompted to enter the first of two millivolt per volt references. (We recommend using -3.0 mv/

volt for the first and +3.0 mv/volt for the second.) Set your reference and enter the appropriate number. As

soon as you press Enter the Model 4215-HS will start reading the reference.

5. Next you are prompted for the second mv/volt value. Set your reference and enter the appropriate number.

Again reading will start as soon as Enter is pressed.

6. When the read is complete, the unit will display “Calibration Done”. Pressing any button at this time will

place the unit back into its normal run mode

The Avg A and Avg B in the item menu is an optional Digital Input function for the display of Force Averaging.

If this function is selected, it replaces IN2 of the standard Digital Input function.

When first selected after power up, the value displayed for average force will be zero. To use the features, the

user must activate the isolated input 2, IN2, of the Digital I/O port connector (pins 11 and 12 – see Digital I/O

Connector in Appendix B). Once the Digital Input has been activated, the unit will begin to display a running

average of the force measured after an approximately 2 second delay. The item “Avg A” refers to the average

force measured, calculated, and displayed on channel A, and “Avg B” refers to the average force measured,

calculated, and displayed on channel B. Opening the Digital Input circuit will stop the averaging.
