2. Handling Precautions
•
••
•
The bypass capacitor for the microcontroller (MCU) and power supply, the jumper plug
for switching the C terminal and 2 connectors for connection with the universal cable
assembly are mounted on the probe header. Be sure to read Section 3, "Using the
Products," before using the probe header to prevent incorrect cable connection, which
could cause incorrect operation or product failure.

•
The MB2144-226-01 is precision-manufactured to improve dimensional accuracy and to
ensure reliable contact. The product is therefore sensitive to mechanical shock, and must
be handled carefully. To ensure correct use in the appropriate environment, use the
products only as instructed in Section 3, "Using the Products".

•
Because ports 0 and 1 of the MCU are connected with cables, they are susceptible to
noise. If ports 0 and 1 are used as input ports, drive the element connected to the ports
with a current of 1 to 2 mA when the port outputs an L level voltage. Be careful not to
read ports only with a pull-down resistor connected, because the values may not be
correctly read.
