5.  BASIC FUNCTIONS OF THE INSTRUMENT 

 

Electronic balance

 

is appropriate for precise measurements mass in laboratory 

conditions with possibility of setting to zero in all measure range. Balance 
calibration is done by 

CAL 

on balance keyboard.

Functions for weighing units (press Units key) 

-

 

select default units of weighing 

<StUn>

-

 

Weighing in grams,  

-

 

Weighing in [mg], 

-

 

Weighing in [ct], 

-

 

Weighing in units from beyond 

SI 

(only: [oz], [ozt], [dwt],  [t], [mom], [gn], 

Access to these units is blocked from factory menu level,

Functions for calibration and weighing modes

 

-

 Counting 

pieces 

< PIECES>

-

 Control 

+/-

 <HiLo>

-

 

Control of deviations % according to standard mass  

<Perc A>,  

<Perc B>

-

 

Thickness of liquids

 <d_Li>

or

 

solids 

<d_Co>

,

 

 

9

 

Choice of criteria of stable result depending on usage conditions 

-

 

Turn off/on system of autozero 

<AUTO>

-

 

Average result of weighing 

<AvE>

-

 

Back light function

<bl>

-

 Beep

Function for using RS 232  

-

 Choose speed of transmission, 

-

 Define sent data as: stable / not stable, 

-

 Continuous work, 

-

 automatic work for RS 232. 

 

Moreover balance can be used to weigh hang loads, print report of calibration, 
check deviation of calibration and print reports of testing thickness of liquids and 
solids.
