the setting values and Nos. are displayed on each colum (chained line section).
(2) How to switch off
Press key.
The buzzer beeps.
The message lasts for about 2 seconds.
Caution
Never remove a probe from a main unit
when Power is ON. Or the electric shocks
may damage the probe and the main unit

When that value is no more necessary,
take「Zeroing」, 「Calibration Standard」.
Stored data can be erased and new data is stored.
(3) How to select 「Cal. No. 」(Calibration curve)
After switching ON, it is capable of getting started on measurements and adjutments when the reading
「START UP PHASE …」 disapeared.
※Generally, thickness meters make errors depending on material formation and shapes to be measured.
To minimize measurement errors and obtain as accurate resutls, 【Zeroing】and 【Calibration standard】
are imeratively adujusted before measuring operation.
Those adjustment is called 「Calibration curve」.
SWT-7200Ⅳis capable of storing up to 10 sets of calibration data and these data can be called and used
when necessary. (the storing place is displayed by a calibration No.)

※Generally, the meter 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 kinds of adjustments of 【Zeroing】and 【Calibration standard】before measuring process.
※Prepare the identical material and shape to a measuring object.
(This is designated as a 「Zero plate」.)

(refer to page 7)
●Press the probe to the 「Zero plate」several times and make sure the measuring result indicates
in the neighborhood of “0”.
When the measured value results in largely off “0”, please try again zeroing from the beginning.
There is a case when calibration is not correctly made.
●“LLLL” displayed on the screen during a time of zeroing means that the calibration point heavily deviates
from the standard.
Please make sure that the metal substrate is not processed with other materials such as plating and
repeat the zeroing until a stable in the neighborhood of “0” is obtained.
※After performing Zeroing, the previous 「Zeroing value」is deleted, and the last entry of 「Zeroing value」
is stored.
