Setting the present measurement value to "0" again
using the forced-zero reference
The tare zero function shifts the present measurement value to "0" again using the forced-zero reference.
This function is enabled when each of two different types of compound are to be weighed, as shown in the
following example.
• Information about whether tare zero is being executed or cleared and shift values after tare zero is
executed are not stored in memory when the power is turned OFF. (If the power is turned OFF during
tare zero, the Unit will be in forced-zero status when the power is turned ON again.)
•
Forced-zero cannot be executed when the display range has been exceeded or a sensor error occurs, or
while no measurement is being performed. (Forced-zero can be cleared but not during RESET input.)
There are two methods for executing and clearing tare zero: using key operations and using ZERO inputs.
●Using key operations
<Executing tare zero>Press the U[UP] Key while forced-zero is being executed and the present value is
displayed to execute tare zero.
<Clearing tare zero> Press the U[UP] Key for 1 s to clear tare zero. (Press it again for 1 s to clear
forced-zero.)
●Using ZERO inputs
<Executing tare zero>Tare zero is executed on the rising edge of the ZERO input ON signal during
forced-zero execution.
<Clearing tare zero> If the ZERO input is ON for 1 s, tare zero is cleared. (Forced-zero is cleared if the
ZERO input is ON for a further 1 s.)
