digits
2. Keyboard: 4-key push button
POWER:
1. Alkaline Batteries: 4 x “AAA” size cells
When all displayed segments of LCD flashed, this indicates the batteries are
low below 4.9V and you’d better to replace batteries;
When “Lo.bAt” displayed, this indicates the batteries are low below 4.7V and
you should replace batteries immediately.
2. AC Adapter: 6VDC, 500mA, with central negative:
3. Work current: ≤25mA
(when voltage in 5Vdc-8Vdc and not include load cell’s consumption)
OPERATION TEMPERATURE: 20℃±15℃
STORE TEMPERATURE: -10℃-70℃
OPERATION HUMIDITY: ≤95%RH (no condensate)
LOADCELL:
Because of more than one load cell can be used on a scale, following are
required on the load cell set to be used with this indicator,
1. Sensitivity: 0.3mV/V --- 3mV/V (must be fit to >0.2uV/display grad)
2. Input Resistor: ≥80 Ω
3. Output Resistor: <10 KΩ
LOADCELL WIRING:
PIN 1: RED, EXCITATION +
PIN2: BLACK, EXCITATION –
PIN3: GREEN, SIGNAL -
PIN4: WHITE, SIGNAL +
