Parameter of channel 1

yyy

Parameter of channel 2

Always enter all the parameters for all outputs. The MMT162 measures

the following parameters:

- water activity (aw)

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

- ppm for transformer oil only (H

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 9 below.
