Load Calibration
Load Calibration
Overview
The Load Measurement function of the Series 4400 System
consists of a precision load cell transducer, mounted on the
load frame crosshead, and a Load Sensor Conditioner, lo-
cated on a section of the console printed circuit card.
The calibration procedure precisely calibrates the load
weighing system for the load cell in use. The system
then is able to provide an accurate load signal which is
automatically ranged during a test over 100% (X1), 50%
(X2), 20% (X5) and 10% (X10) ranges of the load cell
maximum capacity.
A 15 minute warm-up period with system power on and
all circuits functioning, must be allowed before perform-
ing the calibration procedure. This assures that load cell
creep is at a minimum.
The calibration procedure you use depends on the type of load
cell installed. Load cells can be one of the following types:
(a) Self identifying and electrically calibrated.
(b) Self identifying and manually calibrated.
(c) Non-self identifying and electrically calibrated.
(d) Non-self identifying and manually calibrated.
The procedures for calibrating all four types of load
cells are given in this section. These procedures, for the
most part, require you to enter simple key sequences.
