Note: 1.
Terminals 2 and 3 and 10 are not internally insulated. Connect a relay with high contact reliability and insulation (with a minimum
load current of 0.3 mA) or a photocoupler with high insulation (with a residual voltage of 1 V max. and a current leakage of 0.1 mA
max.) to these terminals for external control. The use of an independent power supply is recommended for the Digital Panel Meter.

Safety Precautions

Precautions for Correct Use
Refer to
Safety Precautions for All Digital Panel Meters.
Accessories (Order Separately)
Water-resistive Soft Front Cover
Before mounting the Digital Panel Meter to a panel, attach the water-
resistive soft front cover and mounting bracket to the Digital Panel
Meter properly so that the Digital Panel Meter will maintain IP51
water-resistive standards.
Mounting
Recommended panel thickness is 1 to 3.2 mm.
Mount the Digital Panel Meter by attaching the mounting bracket sup-
plied as an accessory from the rear of the Digital Panel Meter and
hooking the mounting bracket to the Digital Panel Meter securely.
Tighten the mounting screws by turning them clockwise with a tight-
ening torque of 4 kgf·cm (0.39 N·m).
To dismount the Digital Panel Meter, loosen the screws and widen
the hooks.
Mount the Digital Panel Meter as horizontally as possible.
Mounting
Adapter
Soft Cover
Calibration
Calibrate the Digital Panel Meter regularly so that the Digital Panel
Meter can maintain processing accuracy.
Use a standard signal generator with an accuracy of 99.99% min. for
calibration.
For the precise calibration methods, refer to the Instruction Sheet for
the Digital Panel Meter.
Note:
Be sure to use the Water-resistive Soft Front Cover and
mounting bracket together.
Control Power Supply
Use a control power supply with a ripple rate of 10% max.
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.
