(1) To close the load cell relay, press the LOAD CAL
key on the Series 4400 front panel, then press 0 and
ENTER. The LOAD CAL and LOAD BAL LEDs
are both lit when this relay is closed.

*To convert newtons:
1. Multiply by 0.224 808 9
to obtain pounds.
(2) IMPORTANT – After checking pen deflection,
open the calibration relay by repeating the key se-
quence to close the relay: press LOAD CAL, 0,
ENTER on the keypad. The LOAD CAL and
LOAD BAL LEDs go out. A test cannot be
started when the calibration relay is closed.
The voltage generated when the load cell cali-
bration relay is closed is the same as would be
produced by an applied load equal to 50% of
the maximum capacity of the cell when using
