Description
<name> = PT100
D100
F100
PT3916
PT385
USER
:TYPE?
This command is used to select the FRTD standard and other related factors.
When one of the parameters other than USER is selected, the multimeter
defaults to the following factors:
Type Alpha
PT100 0.003850
D100 0.003920
F100 0.003900
PT385 0.003850
PT3916 0.003916
Changing alpha (see :ALPHa), beta (see :BETA), delta (see :DELTa), or Ω at
0°C (see :RZERo) automatically changes the type to USER (see :TYPE).
<NRf> = 0 to 10,000
:RZERo?
This command is used to check and/or change the resistance at 0°C.
Remember that if you change the present resistance value, the FRTD TYPE
will change to USER.
