Calibration procedures
Warning
●
Before using the new instrument or after exchanging the strain gage
applied transducer with a new one, be sure to make calibration.
If calibration is not made, correct measured results may not be
obtained, or it may cause malfunction to the instrument and it may
damage the peripheral equipment.
Moreover, even if calibration has made, there may occur the similar
case as above when the result is not correct. So make precise
calibration again.
●
The calibration for the instrument and “Display value at the time of
minimum analog output”(F
−
21) and “Display value at the time of
maximum analog output” (F
−
22) are not interlocked. In due course,
make check on the setting for F
−
21 and F
−
22 securely.
If neglected, correct outputs may not be obtained, or it may cause
malfunction to the instrument and it may damage the peripheral
equipment.

1. Preparations
According to the Chapter 4. Connecting method, connect the instrument and the strain gage
applied transducer properly, then supply the power.

2. Calibration procedures
Load calibration procedures for the instrument are as follows:
1
Calibration method to register the output (conversion with mV/V) of strain gage applied
transducer at the time of maximum display (weighing capacity) after setting the load to zero
(Initial load condition with tare weight).
2
Calibration method (Automatic calibration for Zero and Span) to register the output of strain
gage applied transducer (conversion with mV/V) at the time of zero load(Initial load
application with tare) at the optional load condition, and also to register the output
(conversion with mV/V) of strain gage applied transducer at the time of maximum display
(weighing capacity).
3
Calibration method (Actual load calibration) to register by the reading output of strain gage
applied transducer, when setting in the condition of zero load applied (Initial load application
with tare) and in the condition of actual load applied individually.
