EDX Features

Enclosure: Designed to NEMA4X/IP55. Suitable for continuous outdoor use.

Accuracy: 0.1% of capacity.*

Repeatability: 0.1% of capacity.*
* Normal resolution mode.

Ultimate overload: See table above

Safe overload: 200% of capacity

Body protection: Aluminum capacities are anodized. Alloy steel capacities are electroless-nickel plated.

Bearings: Unmatched repeatability attained by needle bearings in shackle pin holes up to EDx-10K. Precision machined shackles act as inner race.

Shackles: Forged industry standard anchor shackle bows, galvanized finish. Models up to EDx-10K use precision machined shackle pin. Higher capacities use forged pin.

Display: 128 x 64 dot-graphic LCD display shows up to 6 digits 1.0” (26 mm) high plus annunciators and softkeys. Digits are .11 inches (7mm) thick for unmatched readability.

Display update rate: 2 times per second.

Connector: Recessed sealed connector may be used for direct serial communications or connection to a Communicator remote.

RS-232 / RS-485 communication: Print or extract data easily. Continuous output can drive a scoreboard. Configurable poll character.

Calibration: Traceable to the National Institute of Standards and Technology. Certificate included with curve of readings. Passes only with three consecutive confirming runs, with all points in specification.

Battery life: 320 hours typical use with two C-cell alkaline batteries. 40 hours typical with Radio Link system.

Operating temperature: -4° F to 140° F (-20° to 60° C)

Included with instrument: Shipping/storage crate(s), batteries, manual and certificate of calibration.

Options: 2.4 GHz radio board. Display backlight.

Radio Specifications

FCC Certified: For unlicensed low power devices. No radio licensing or permits required for normal operation.* (In the US and Canada. Check local ordinances in other countries.)

Frequency: 2.4 GHz spread-spectrum operates between 2.402 – 2.478 GHz. Continuously and automatically changes frequencies many times per second for consistent, reliable communications.

Output level: 10 mW (20 dBm)

Display update rate: 2 times per second with single dynamometer. Multiinstrument networks result in reduced updates.

Number of networks: 63 remotes can operate independently in the same airspace with unique channels.

Number of links remote can control: Up to 15 addresses are available per network channel.

Configuration: Address and Network channels are front-panel configurable.

Antenna: Integral antenna. Range Open-air – Up to 300 feet, line-of-sight. Indoors – Dependent upon installation site with 150 feet common.

Approval: FCC ID: KQL-PKLR2400. CAN ID: CAN2268391158A
