the panel meter with “15 range”.
: Installation categoryⅡ,
The mark on the label indicates the measuring
range in the specification of item 1.
Do not disassemble or touch the interior
while the power is ON.
This may cause an electric shock.
Incorrect handling may cause
death or injury.
On the AP-101, connect the control inputs(HOLD,Decimalpoint)to
base-isolated devies when the input signal is 70V DC or more.
