1.7 Weighing Mode

.⑴Weighing with Tare

Tare Method：

Place the container on the platter，press TARE key。

.⑵Zero Set Range

Initial Zero ±The（2％，5%，10%，20%）Capacity

Zero Set Range ±The（2％，5%，10%，20%）Capacity

1.8 Battery Consumption Time

Battery specifications 6V/4AH, battery charging time 16 hours, 25 hours continuous use time.

When the battery voltage drops below 5.3V, the low battery indicator lights. For the protection of

battery over discharge, when the battery voltage is lower than 5.6V, the automatic shutdown.

2、Test Mode Introduction

I、 Power on to Enter Calibration Mode

Press [CAL] key, then press [ON/OFF] key and enter cal mode.

Display [ CAL ] three times, then show [C-1].Press [Zero] or Numeric keys to select

one of C1~C5 item, press [Tare] key to get into C1~C5 mode.

Notice：Because the keyboard of the scale will test the key value and the battery

voltage when enter into CAL mode, please unpress the [CAL] key, and no key will be pressed

between display [CAL] and dsplay [C1].

When keyboard can not be used, please try again.

II、 C1 Set Weighing Specification

C1：Weighing Specification Set：0～34

Display [C1 x ] Showed In Table 1 and Table2.

III、 CLEAR MEMORY

Press [Tare] Key to Initiate EEPROM.

IV、 C3 Calibration

Display [ULoAd]

Press [Tare] Key, Confirm Zero Point。

Display [LoAd]

Load the poise, press [Tare]and wait a few seconds. If the weight loaded is just the

same as the full range, press [Tare] complete this calibration. Or you should modify the value

through Nemeric Key and Press [Tare] Key.

Notice：Calibration weighting value should not great than 10% of capacity.
