Types of Errors and Corrective Actions
The type of error on the instrument can be identified by the lighting status
of the LEDs on the junction box. If an error occurs, follow the corrective
action below. If the instrument needs to be repaired, contact your nearest
YOKOGAWA dealer.

This mode detects the abnormal internal temperature of the junction
box and reduces power consumption. The current cannot be measured
correctly in protection mode.
Set temperature:
80 °C (typical)
Hysteresis:
10 °C (typical)
Remove the sensor from the conductor to be measured and wait until the
temperature of the Junction box drops. If pressing any key on the junction
box, it will return to the normal state, so demag/auto-zero adjustment
will be executed again. In addition, it is recommended to calibrate the
instrument because the internal parts may be stressed by heat.
