is damaged or missing, contact your sales representative or
our sales office directly.
2Overview
The A2200 series digital power meter is a compact 4 1/2-digit
indicating meter that meets DIN standards for external
dimensions. Power is +5 V to 24 V DC type. The maximum
indication is a 19999.
2.1 Type Configuration
2.2 Checking the Accessories
The A2200 series comes with an Operation Manual (1 copy).
Should you have any questions about the manual, please
contact your sales representative or our sales office

2.4 Description of Terminals
2.4.1 Terminal Connection Diagram
2.4.2 Connection Method
The connection terminal of the A2200
series panel meter's terminals is
located inside the case.
When connecting a wire, insert it into
the case from the rear of the meter and
fasten it with a screw using a Phillips
screwdriver from the top of the rear of

Recommended covering stripping
size: 6 to 7 mm
3Decimal-point Setting Method
* CAUTION
Be sure to turn off the panelmeter before changing the
decimal point position.
4Calibration Method
To calibrate this panel meter, a voltage/current generator
with an accuracy of ±0.01% or higher is required. Calibrate
it using the following procedure under ambient conditions
of 23℃±5℃and 35 to 85% R.H.
(1) Connect power to the meter and run it for more than 20
minutes.
(2) Conduct a full-scale adjustment
Apply a voltage or current equivalent to a full scale of
19900 to the input section and turn the full-scale volume
knob (figure below) so that the reading shows "1990 0."
Then apply voltage or current of the negative polarity
to check that the reading shows "-19900±(0.1% of FS)."

Insert a flat-blade screwdriver or the like into the small
hole in the lower part of the front panel acrylic section
and pry the front panel out.
When putting the front panel back into the instrument,
fit in the lugs in the upper part of the acrylic section
first.
The stud pin at the lower right is a decimal-point switch.
