9.4.5 Net/Total  
 
This function allows the user to see the total of all the net weights, the value 
of which is displayed on smaller digits above the main display. The current 
net weight is shown on the main display. The [Tare] key functions the same 
way as in the normal weighing.  
 
Steps: 
 
• Press [Mode] and then [Up] or [Down] to select Net/Total.  When 
“NET/TOT” is displayed press [Enter] to enter the function. The display 
will show zeros in both the display areas...

DENSITY OF SOLIDS    
 
To perform the density of solids test, the user must have a method to 
immerse the sample in the chosen liquid. The density of the liquid must be 
known or determined from a look-up table. 
 
For water and ethanol the density will be calculated based on the 
temperatures entered using the numeric entry method (see section 7.1) 
 
Steps: 
 
• Press [Mode] and then [Up] and [Down] keys to select density 
 
• Press [Enter] to enter Density mode. 
 
• Press the [Up]...

DENSITY OF LIQUID     
 
When finding the density of a liquid, it is necessary to weigh a sample of 
known volume in air and then in the liquid. The volume of the sample must be 
entered by the user. The last known volume is stored for use at any time. 
 
If using the density determination kit, the volume of the plumb is marked on 
its support, i.e. 10.123 
 
Steps: 
 
• Press [Mode] and then [Up] and [Down] to select Density 
 
• Press [Enter] to select the Density mode 
 
• Use [Up]...

10.0  CALIBRATION 
 
The PGW XXXe series can only be calibrated with an external mass.  The 
PGW XXXi series can be calibrated with either an internal mass (default 
method) or an external mass (if setup by the user to do this).   See the User 
Parameters section. 
 
10.1 MANUAL CALIBRATION 
 
Pressing the [Cal] key will start calibration. Calibration can also be initiated by 
a change in internal temperature or a set time period as determined by the 
user (see section 13.5). 
 
10.1.1...

10.2 AUTOMATIC CALIBRATION 
 
The balance will have the ability to calibrate (or ask for calibration)\
 when the 
balance has automatic calibration enabled and the conditions of the 
automatic calibration have been meet.  
 
Conditions that will cause an automatic calibration are: 
 
1. Internal temperature change greater than a preset amount, typically 2ºC 
for Precision balances.  
2. Time since last calibration exceeds a preset time, typically 4 hours or 15 
minutes after power is...

11.0  RS-232 INTERFACE 
 
The balances have the ability to send or receive data over the serial interface. 
 
The weighing data can be sent over the interface either automatically or when 
the user presses the [Print] key. 
 
The user has control over what data is to be printed.  
  
The following gives a description of the RS-232 interface. 
 
HARDWARE 
 
The RS-232 interface is a simple 3 wire connection. The input and output 
connections are: 
 
Connector:   9 pin D-sub miniature...

Any of these can be printed on any of the 15 lines available.  Not all items 
need to be used and any one can be used more than once (see section 13.3). 
 
The data for each form will be preceded by a start-of-header  
character (01)...

INPUT COMMANDS USING REMOTE KEYS 
 
The balance can be controlled with the following commands sent using 
remote keys such as from a PC. The commands must be sent in upper case 
letters, i.e. “KT” not “kt”. Press the Enter key of the PC after each command 
(the action of Carriage Return is denoted as  as shown below). 
 
Basic Input Commands: 
 
!KT

12.0  ERROR CHECKING 
 
During weighing the balance is constantly checking to see if it is operating 
within the limited parameters.  The errors likely to occur are: 
 
 A/D counts below lowest allowed value 
 A/D counts above highest allowed value 
 A/D not operating 
 Maximum capacity exceeded 
 
Other errors may be detected during special functions or operations.  These 
will be described in the section that applies. 
 
Error messages and the reasons are: 
Concerning A/D counts...
