The following scenarios are possible:The following scenarios are possible:
• Make sure the rear panel OVP setting is in the “Normal” position. If the OVP switch is in the “SET” position, the meter might show the OVP setting, not the output value. For OVP details, please refer user manual page22.
• If you are using Channel 1 or Channel 3, make sure the meter switch on the right side is in the correct position. Channel 1 and 3 share the same meter.
