|---|---|
| The input is of the Load Cell/Strain Gauge type. With transducer excitation voltage of 9.6 volts @ 160mA to drive 6 x 350R bridges | |
| Compensation by ± sense wires for cable and safety barrier losses down to 3V excitation | |
| Load cell sensitivity is preset via DIL switches to 0.5, 0.8, 1.0 1.25, 1.5, 2.0, 2.5, 3.5, 5, 10, 20, 50, 100 or 200mV/V | |
| Initial offset is no greater than ± 0.15mV (15uV/V) which is cancelled during auto calibration | |
| Speed | is 10 readings per second with a digital filter to reduce speed |
| Accuracy | is 90 days ± 0.08% of reading, +/- 0.05% FSD being typical |
| Drift | is 0.002% per degree C @ 2.5mV/V typical |
| Resolution | 15 bit/ 4.5 digits |
| Contact inputs | are available for auto tare, print and peak hold reset and are volt free |
| Analogue Outputs | |
| Drive | 4-20mA up to 1Kohm and 0-10 volts up to 2mA |
| Accuracy | 4-20mA + 0.15% of range, typical. 0-10V ±2% before calibration |
| Resolution | as for display up to 13 bits/4.5 digits. Settling time 350mS to within 1% of step change |
| Isolation | ±130V RMS or DC max to analogue input or any other port |
| Power Supplies | |
| LS1 | 110V-120V AC or 220/230V AC 50-60Hz 10W |
| LS3 | 9-32V DC 10W isolated |
| Data Retention/Protection | |
| Retention | 10 years for set up values, minimum of 100,000 write cycles |
| Protection of data and function(s) | Watchdog timer giving repeat auto resets. Impending power detection and hold off. Keypad security and time out |
| Other Options & Accessories | |
