Section 3. Setup and Calibration Guide

Power connections:

The PC-400 is powered from a wall mounted transformer or the internal

rechargeable battery. The transformer has a power cord which plugs into the

power jack located on the back of the scale.

RS-232 Connections:

The PC-400 has a standard RS-232 output. To use this feature, the optional RS-

232 cable is needed. Plug one end of the RS-232 connector into the RJ-12

connector located on the rear of the scale. Attach the other end to your

computer or printer.

Calibration and Parameter Setup:

1) After applying power to the PC-400, remove the platter, turn the scale over

and remove the calibration bolt as shown above. Place a thin blunt object

through the hole and press straight down. The scale should enter the

Setup/Calibration mode, and the scale should display “div 2.5” (or “div 5.0“or

“div 10” depending on the scale resolution.)

2) Turn the scale upright, replace the platter and press the UNITS button twice.

The scale should now display “CAL 0”.

3) Remove any unnecessary weight from the scale platter. Press ZERO. Wait

for the scale to count down from “7” to “0”. If the scale detects motion, the

display will restart the count. When finished, the display will return “CAL F5”.

NOTE: If “r9 Err” appears on the display, the calibration zero is out of range.

Press ZERO to clear this error. Refer to the analog setup section for

additional information.
