5. PREPARATION
5‑1. Preparation of the zero plate
Prepare the substrate which is the same kind, thickness and shape with an object
to be measured.
The attached zero plate for checking the Meter, Aluminum 1050, is used for the
operation check of the Meter.
Prepare the substrate of an actual object to be measured.
・
Same kind
The same kind of material as the substrate of an object to be measured
・
Same thickness
Nearly the same thickness as the substrate of an object to be measured
・
Same shape
The same shape in pipe diameter, curvature, geometrical shape, etc. as the substrate
of an object to be measured
・
Size
Substrate with an enough area on which the probe can be easily operated
・
Surface condition
Untreated (unoxidized etc.) substrate having smooth surface
Remove rust, dirt or dust, if any.
5‑2. Connecting(Disconnecting) the probe
Carry out the connection (disconnection) of the probe by the following procedures.
・
Be sure to keep the Power OFF.
・
The probe cannot be substituted with other probe.
Use the probe which is the same number with the Meter number.
◎ Connecting method
Insert the probe into the probe
connector keeping the wide cut
right ward and tighten it by turning
Ａ clockwise.
◎ Disconnecting method
Release by turning Ａ counter‑
clockwise and calmly pull the probe
out of the connector.
Don't pull the cord as it
causes breaking of cord.
※
When the probe is not connected to the Meter or any system is out of order even if the probe
is connected, the indication changes as follows after power ON .
If the probe is disconnected in power ON condition,
「
PE

is indicated on the display and power
is automatically cut off. (
「
PE
」
is abbreviation of Probe Error.)
