(3) Zeroing
It is capable of getting started on measurements immediately after the message of 「START UP PHASE」
has disappeared as described on page 12.
However, it may make errors depending on material formation and shapes to be measured. To minimize measurement
errors and obtain as accurate results as possible please be sure of carrying out 2 points of adjustments of
「Zeroing」 and 「Calibration standard」 before measuring process.
※
Please prepare for a Substrate plate the identical material, quality and size to a measuring object.
(This substrate plate should be designated as a 「Zero Plate」)
◆ Press ZERO key.
The buzzer emits a beep sound. It stopes its LOCK function of LOCK/DELETE key
and changes to one data “deletion”.
Press the probe on the above 「Zero Plate」 while
the message is indicated on the screen. ( about 20 second)
The buzzer beeps.
Zeroing is in process.
The reading shows that the unit is set to
measure on substrate material of Ferrous by
connecting a probe of the 「Fe」series.
Measured numerical value
When the measuring value results in largely off
the “0”, press LOCK/DELETE key to
delete the latest data out of measured values.
It indicates “—-“to delete all data.
「Cal. No._ 」 for storing values of
「Zeroing」 and 「Standard Calibration 」
● Repeat a measuring process 2~10 times by pressing
the probe to 「Zero plate」. (A measurement value is
Remove the probe from 「Zero plate」
displayed whenever a probe is pressed)
◆ When a measuring process reaches the 10
th
time, the
buzzer beeps and zeroing automatically finishes without
pressing ZERO key.
