=
Quantity of channel 1
yyy

Quantity of channel 2
Always enter all the quantities for all outputs. The MMT162 measures
the following quantities:
-
water activity (aw)
-
temperature (T) (metric unit: ºC, non metric unit: ºF)
-
ppm for transformer oil only (H
2
O)
Example:
asel
Ch0 aw lo : 0.00 ?
Ch0 aw hi : 1.00 ?
Ch1 T lo : -20.00 'C ?
Ch1 T hi : 80.00 'C ?
Set Analog Output Mode (mA/V)
The
AMODE
command can be used to change the analog output mode
of channels 1 and 2. When used without parameters it displays the
current settings and with parameters new settings can be set. The
available parameters are listed in Table 7 on page 33 below.
