5.Display/setting items

•Output display: 16-character × 2-line dot-matrix LCD (with back light)

Indicating unit: 2 units can be selected from the flowing units: flow velocity, instantaneous flow rate, total flow (forward/reverse/difference flow), total count, %, custom unit.

•Setting: Various parameters can be set without opening the converter housing using 4 infrared switches (password can be set)

Settable also with AF900 Handheld terminal

•Damping: 0.5 to 60 seconds (settable in increments of 1 second)

•Zero adjustment: Adjustable with infrared switches

•“Field re-verification” Mag-Prover– Toshiba’s Zero span calibration tool :

Allows unit to be re-calibrated and verified using internal software program (for more information contact Toshiba International Corp.)

• Operation at power failure:	Various setting values are stored in non-volatile memory.
	Current output	0mA
	Digital Output	OFF (contact open)
	Display	Unlit

6.Other items

•Mass: Approx. 18 lb (8kg) (including a mounting fitting)

•Ambient temperature: -4 to 140 °F (-20 to 60 °C) (storage temperature: -13 to 149 °F (-25 to 65 °C))

•Arrester: Included in the power supply circuit, current signal output circuit and digital I/O circuit.

•Terminal block structure: 21-pole, screw connection type (M4 screw)

•Housing material: Aluminum alloy

•Painting: Acryl resin baked painting with pearl gray color

•Structure: IP 67

•Cable ports: G (PF) 1/2 female thread with cable connection

Adaptable cable diameter: φ0.433 to 0.512 inch (φ11 to 13mm)

Material: Nylon 66

•Vibration resistance: No resonance point exists when the following vibration is applied: 10 to 55Hz with amplitude of 0.07mm,

No problem occurs when vibration of 30Hz, 29.4m/s2 is applied in each direction for 4 hours each.

Note: If the flowmeter is intended to be used in a location where vibration is applied constantly, contact Toshiba.
