Configuring Measurement Parameters

Set Mixing Ratio

Use the MIXRATIO command to set the mixing ratio of SF

and the

other gas.

MIXRATIO [ratio]<cr>

where

ratio

Amount of SF

in the measurement environment, range

0 ... 100%.

Example:

mixratio 50

MIX RATIO : 50.00 %

Set Molar Weight of Other Gas

Use the N2MOLW command to set the molar weight of the other gas

(not SF

) in the measurement environment.

N2MOLW [weight]<cr>

where

weight

Molar weight of the other gas in kg/mol. The default is

2.8013401e-02, which is the molar mass of N

Example:

n2molw

OTHER GAS MOLAR: 2.8013401e-02 kg/mol ?

Set Pressure Normalization Temperature

Use the PNORMT command to set the temperature that is used to

calculate the normalized pressure parameter.

PNORMT [t]<cr>

where

Temperature in Celsius, range -100 ... 100. The default is 20.

Example:

pnormt 20

P_NORM_T : 20.00 'C

1 2 ... 33 34 35 36 37 38 39 40 41 42 43 ... 62 63
