Calibrating Specific Density (Densometer) 
To accurately calibrate the densometer the temperature reading must be 
correct. Always calibrate the temperature before calibrating the density. 
Using the ‘K’ Factor switch to calibrate the densometer: 
Step 
ACTION 
RESULT 
1 
Ensure that the nozzles are 
hung up 
Dispenser in idle state 
2 
Press and release the „K‟ 
Factor switch, in quick 
succession, until „LP6‟ is 
displayed in the price 
display. 
The volume display indicates 
„00000‟. 
3 
Press and hold the „K‟ factor 
switch. 
A digit, of the volume display, 
will begin to increment. 
4 
When the digit is correct, 
release the „K‟ Factor 
switch. 
5 
Repeat steps 3 & 4 until the 
volume display reads 1. 
The volume display indicates 
00001. 
5 
Press and release the „K‟ 
Factor switch, in quick 
succession, until „den‟ is 
displayed in the price 
display. 
The LPG pump will start and 
the volume display indicates 
the specific density @ 15ºC. 
6 
Press and hold the „K‟ factor 
switch. 
A digit, of the displayed 
setting, will begin to 
increment. 
7 
When the digit is correct, 
release the „K‟ Factor 
switch. 
8 
Repeat steps 6 & 7 until the 
volume display reads the 
correct density as measured 
by a hydrometer and 
corrected to 15ºC. 
The volume display indicates 
the correct specific density. 
 The C4000 will reset itself if the „K‟ factor switch is left for 
more than 10 seconds. 
Pressure does have a small effect on density so you will notice that the 
LPG pump will run while the density is being calibrated. This ensures that 
the density is always being measured and calibrated at approximately the 
same pressure.
