BACKSIDE INSTRUCTION

DWP102N:

TTL (low-active) is transmitted here(optional). The DB-25 connector of the
external relay board (if ordered) should be plugged in

DWP102NS:

DWP-102NS use water proof joints which need to get through the round
joints and connect onto the PCB
The recommend (from left to right):

1) power plug 2) Com2 RS232

3) Com1 RS232 (RS485 optional) 4) Loadcell

4. GETTING STARTED

In order to obtain an accurate weighing result, the weighing platform,
(hereinafter referred as platform) must be placed on a strong and level
surface. Avoid using the platform and this instrument (hereinafter
collectively referred as scale) in environment where excessive wind flow,
vibration and extreme temperature change exist

General Warning: -

 The instrument is not an explosion proof device.
 The instrument is not a water proof device.
 Do not open the instrument, no user serviceable parts inside.

Always contact your dealer for service.

 The instrument not to be subject to shock, excessive vibration

or extremes of temperature (before or after installation).

4.1 BUILT-IN RECHARGEABLE BATTERY

The instrument is equipped with a built-in rechargeable battery. Before first
time use, recharge it for at least 8 hours to ensure the best battery
performance.

4.2 POWER ADAPTOR

Before plugging in the power adaptor, check and make sure the input
voltage of the adaptor matches with output voltage of the electricity outlet. If
not, contact your dealer immediately.

4.3 CONNECTING OTHER DEVICES1

4.3.1 Connection with Weighing Platform (Load Cell)
