Page 6: Power Supply
POWER SUPPLY AC Adapter If the indicator is powered by an adapter, plug the adapter directly into the “DC” pin located at the bottom of the indicator. We recommend to plug into a wall outlet to avoid interference with other wirings. Battery (Optional) If you have an indicator with the rechargeable battery option, please charge the internal battery fully before first time use. -

Page 9: Operating Instructions
OPERATING INSTRUCTIONS Power On ● Turn on the power by pressing the power button for 2 seconds. Once on, the scale will flash the voltage and then begin to auto-check and count down from 0-9 sequentially before entering the weighing mode Note: Anything on the scale before powering on will automatically be tared out. - Page 10 Counting Function ● The counting function is used to count a high volume of identical parts. You can do this by setting a sample and then either adding to the sample or taking away from the sample to count the number of objects on the scale ●...
- Page 11 Hold There are 4 different hold functions you can choose from in the C11 parameter 1. Peak Hold: Grabs the highest weight (for materials testing, ie. tension and pulling force) ● Press the HOLD key then add weight to the scale ●...

Page 28: Troubleshooting
TROUBLESHOOTING Error Codes Error Reason Solution 1. Overload 1. Reduce the weight 2. Wrong connection with load cell 2. Check load cell connection UUUUUU 3. Load cell has quality problem 3. Inspect load cell; Check the input/output 4. See Q&A section 1. -
Page 29: Q&A
Q&A The scale does not turn on Make sure the power cord is plugged in, and that there is power. One easy way to test this is by connecting another appliance to the same outlet and see if it’s operational The reading goes negative when a load is applied Try interchanging the Sig+ and Sig- wiring connected to the load cell and/or junction box (if one is used) -
