FI<cr> Inhibits certain front panel functions.
UM<cr> Causes Stations to be displayed in millibars.
UP<cr> Causes stations to be displayed in Pascals.
UT<cr> Causes stations to display in traditional units.
GAS
GFx<cr> Clears Station x from gas (Argon) operation.
GNx<cr> Sets Station x for gas (Argon) operation.
HOT CATHODE
AH<cr> Auto Mode For Hot Cathode Gauges.
C2<cr> Cancel filament enable by 24 volt signal
EB<cr> Enable "both" modes of filament auto turn off.
E2 Enable control of filament by 24 volt signal.
EH<cr> Enable Hot Cathode Gauges (shutdown mode).
FF<cr> 3D or 3E Filament OFF.
FN<cr> 3D or 3E Filament ON.
FNn<cr> Select filament "n", #1 or #2 (3E only).
GF<cr> 3D or 3E Degas OFF.
GN<cr> 3D or 3E Degas ON.
GNxxx<cr> 3D or 3E Degas ON for "xxx" minutes, 255 max.
SWx<cr> Make sensor switch setting equal "x" (logical).
SD<cr> Send HC drive & I em
SS<cr> Stop HC drive & I em
FM<cr> Use of Soft 1.37 w/older units. Manual filament selection.
FR<cr> Use of Soft 1.37 w/units with front panel filament select.
RS<cr> Read switch position. Response "0" through "7".
R3Dx<cr> Set full scale linear rec out. x is full scale range (exponent).

ED<cr> End Leak Rate data stream (but not the test).
EL<cr> Stops Leak Rate test.
LR<cr> Starts (or restarts) Leak Rate test. Time = 0.
RL<cr> Read Leak Rate value periodically. "LR=nnnn"
where nnnn is the leak rate in microns/hr.
OUTPUT FORMATS
RF<cr> Disable 0-10V outputs. They become indeterminate.
RN<cr> Enable recorder outputs.
R1EL<cr> Recorder output of 1Es & 1Fs to be logarithmic.
R1EN<cr> Recorder output of 1Es & 1Fs to be linear.
R2AC<cr> Recorder output of 2As to be 2C traditional.
R2AL<cr> Recorder output of 2As to be logarithmic.
R2AN<cr> Recorder output of 2As to be linear to (1) Torr.
