QHW digital weighing scales user’s guide

 

- 12 - 

 
The scale has 6 parameters that can be set by the user.    These allow the user to set 
the scale to: 
•  Display the weight in other increments of weight to minimize the affects of 

vibration, wind or other environmental conditions. 

•  Control the back light on the display.  It may be necessary to turn the backlight 

off to maximize battery life. 

•  Set the Accumulation to Automatic, manual or set the RS-232 interface to 

continuously print the weight. 

•  Set whether accumulation when print 

•  Set auto zero range 

•  Select another weighing unit than the standard. 
 
To set parameters press the FUNC and PRINT keys at the same time.     
 
The display will show "Inc    xx"    The first value shown is the default scale increment 
value.    To select a different increment value press the TARE/

Ï key to change the 

value then press the ZERO/ENTER key. 

For example on a 15kg scale the standard increment is 0.5g, the value can be 
changed to 1.0g or 2.0g. 

 
The next parameter is control of the backlight.    The standard is to have the backlight 
operate automatically, turning off when the scale is not used.    The backlight can be 
set to be "EL    On" , "EL    Au" (Automatic)    or "EL Off".  The maximum battery life 
is achieved with the backlight turned off. 
Press the TARE/

Ï key to change the value then press the ZERO/ENTER key. 

 
Automatic accumulation is next.  With "Au On" the memory will accumulate the 
weight automatically,  "Au  Off"   will enable the manual accumulation and with "P 
Cont" set  the RS-232 interface will send the weight continuously and the 
accumulation function is disabled. 
Press the TARE/

Ï key to change the value then press the ZERO/ENTER key. 

 
Whether accumulation when print is next, With “ACC ON” when you print it will 
accumulation, “ACC OF” will only print without accumulation. 
Press the TARE/

Ï key to change the setting then press the ZERO/ENTER key. 

 
Auto zero range is next, you can select 0.5d, 1d, 2d and 4d. 
Press the TARE/

Ï key to change the setting then press the ZERO/ENTER key. 

 
The displayed unit of weight is set next.  The scales are normally calibrated and 
display in kilograms, however they will show the weight in grams, ounces or pounds 
and selected by this function.     
Press the TARE/

Ï key to change the value then press the ZERO/ENTER key. 

 

When the scales are set to display in other units of weight the accumulation function 
is still keeping the weight in kilograms.
