AMODE/ASEL

Use the serial line to select and scale the analog output quantities. Check
the analog output modes with the AMODE command.

AMODE

Example:

>amode
Ch1 output : 0...1V
Ch2 output : 0...1V
>

Select and scale the quantities for the analog outputs with the command
ASEL. Note that the optional quantities can be selected only if they have
been selected when ordering the device.

ASEL [xxx yyy zzz]

where

xxx = Quantity of channel 1
yyy = Quantity of channel 2
zzz

= Quantity of the optional analog output channel 3

Always enter the quantities for all outputs. The MMT330 measures the
following quantities:

- Water activity (aw)

- Temperature (T) (metric unit: ºC, non-metric unit:ºF)

Use the ASEL [xxx yyy] command as shown in the example below when
using a device with two analog outputs.

Example:

>asel aw t
Ch1 aw low : 0.00
Ch1 aw high : 1.00
Ch2 T low : -40.00 'C
Ch2 T high : 60.00 'C
