- Page 6 SEKO Forklift Scale systems utilize Rinstrum's NTEP certified Scale Indicator producing display errors of less than +/- 0.03% and NTEP certified S-beam type load cells producing signals with +/- 0.03% error. The SEKO weigh module low-friction mechanical design allows better than +/- 0.1% displayed weight error in practice.
- Page 7 Passcodes and Operator Lock-Out ( Normally NOT USED ) The instrument has two levels of passcodes to provide restrict Setup via the keypad. Full Setup Passcode (For calibration and Technician Access) Setting a passcode for Full Setup restricts any access to Full Setup. Full Setup passcode can also be used to access Safe Setup.
- Page 8 POWER CHECK and Troubleshooting 1. POWER SOURCE Check to be sure the system has primary DC power applied. Power should be between 8Vdc and 18Vdc if powered from truck electrical or greater than 6Vdc using fresh "AA" batteries if utilizing internal battery pack. 2.
- Page 9 This condition can produce an open circuit Voltmeter indication of satisfactory Voltage, because the resistance of degraded continuity is difficult to detect in an open circuit. Degraded circuit/wire/ ground connections can often be detected by detecting the difference in Voltage at the load when OFF and when ON.

Rinstum-R320/323 Indicators. Firmware K356 v4.16 (Last revision 25 May,2017) General comment: Your SEKO Weighing System can provide 99.9% or better accuracy and repeatability for most of your onboard weighing activities. CALIBRATION The Calibration process is performed in three steps: The first step establishes ZERO - the unloaded forks. We are actually weighing the empty forks to establish the ZERO (0) weight display. - Page 21 " 0 " ( ZERO ) " CAL " ( Press until is displayed ZErO "T" (Tare) Press (ZERO) to select " " SELECT "(some flashing number)" Press and the display will show "f/OK" ZErO Lift the empty forks to the weighing point and press to store the "...

- Page 23 Testing for Repeatability and Adjusting for Accuracy: It is good practice to lift your test weight several times to determine the repeatability of the machine, Scale Set Up and Driver Operation. If convenient, lift two or three other known weights of different ranges to assure yourself that the Weighing System weighs consistently and accurately across a range of weights.
