6. Troubleshooting

Follow the actions described in this chapter to inspect the instrument and troubleshoot the
problem if the load does not operate normally. Contact Faithtech authorized agent or Faithtech
after-sales if the information provided in this manual does not resolve the problem.

Table 6-1 Load fault check table

Problem

Possible Cause

Solution

Measurement accuracy is not
within SPEC.

Measurement swings due to
aged components.

Do calibration.

Loading accuracy is not within
SPEC.

Output swings due to aged
components.

Do calibration

Overtemperature Protection
OT

1. The ambient temperature
is too high.
2. Bad ventilation.
3. Fan damaged.

1. Operate the instrument within an ambient
temperature of 0 - 40°C.
2. Ensure the instrument is well ventilated.
3. Contact Faithtech authorized agent or
Faithtech after-sales.

Overpower Protection OPP

Load power exceeds set

Decrease loading or increase OPP setting

Overcurrent Protection OCP

Load current exceeds set

Decrease loading or increase OCP setting

Overvoltage Protection OVP

Load voltage exceeds set

Decrease input voltage or increase OVP
setting

Temperature Switch E01

1. The ambient temperature
is too high.
