◎ About reading display
When placing batteries in the unit, the messages and warning below on the screen may be indicated.
And these are not breakdowns, wait until the reading disappears with a beeping sound.
Batteries have run out when the display on the unit indicates the mark listed below.
Replace with new batteries.
In case of using FN-325 probe:
After Power source switched to OFF at Automode,
AUTO is indicated on the display and when Fe or NFe substrate

（３） Zeroing
It is capable of getting started on measurements immediately after the message of 「START UP PHASE」
has disappeared as described on page 9.
However, it makes 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. CAL/DELETE key changes to one data “deletion” function.
Press the probe to the Zero Plate.
The buzzer beeps.
Zeroing is in process.
The reading shows that the unit is set to
measure on a substrate material of Ferrous by
connecting a 「Fe-325」 probe, or a 「Fe」 series
ｐrobe.

(６) 2-foil calibration when “Zeroing “ is difficult to perform.
In case zeroing is difficult to perform such as measuring the thickness of the film on the rough surface of Blast-steel plates,
a calibration method using 2 different thicknesses of standard plates pinching a thickness of the object is defined as
｢JIS K5600｣Standard. This calibration method complies to the regulations.
Caution
It is not possible to use both this calibration method and other calibration ones together, or mixing them together.
Should were the methods taken, measuring results could be the wrong values.
Prepare the same blast-steel-plate in material as the objective base or, a rough face on non-ferrous base like
aluminum and 2 different thicknesses of Thickness standards.
