Table 1. AMODE command
Syntax Description
amode [CH1mode CH2mode] [CH1lowlimit CH1highlimit] [CH2lowlimit CH2highlimit]<cr>
where
CH1mode / CH2mode

0_5V (Output scale 0 … 5V)

0_10V (Output scale 0 … 10V)

X_YV (Output scale lowlimit … highlimit)

CH1lowlimit / CH2lowlimit
Low limit for output voltage
CH1highlimit /CH2highlimit
High limit for output voltage
Use the amode command to show or set the analog output mode
Example: Channel 1 limits configured as 1 ... 6 volts and Channel 2 as 0 ... 5 volts
>amode x_yv 0_5V 1 6
Ch1 Analog out mode : X_YV
Ch2 Analog out mode : 0_5V
Ch1 low limit       : 1
Ch1 high limit      : 6
>
Example: User prompted to accept currently used channel limits or enter new limits
>amode x_yv
Ch1 Analog out mode : X_YV
Ch2 Analog out mode : 0_10V ?
Ch1 low limit       : 0 ?
Ch1 high limit      : 10 ? 1

Table 2. AERR command
Syntax Description
aerr [level1 level2]<cr>
where
level 1 level 2
Error levels for analog output channel

Use the aerr command to show or set the analog output error levels.

Examples:
>aerr
Ch1 Error level     : 3.6
Ch2 Error level     : 3.6
>
>aerr 3.85 3.86
Ch1 Error level     : 3.85
Ch2 Error level     : 3.86

Table 3. ASEL command
Syntax Description
asel [q1 q2] [lo1 hi1 lo2 hi2]<cr>
where
q1 q2
Analog output channel parameters 1
lo1 lo2
Low limits of scaling
hi1 hi2
High limits of scaling

Syntax for single-parameter transmitters:

asel [q] [lo hi]<cr>
where
q
Analog output channel parameter
lo
Low limit of scaling
hi
High limit of scaling

After you have defined the measurement parameters with the calcs command, use the asel command to show or set the parameter output by the analog channels, and the scaling that is used. If you do not enter scaling limits, default values are used. Valid parameters are: RH, T, TD, TDF, A, X, H, TW, PWS, PW, and NONE. The NONE parameter disables analog output and output is forced to error level.

Examples:
>asel
Ch1 Quantity        : RH
RH lo               : 0
RH hi               : 100
Ch2 Quantity        : T
T lo                : -60
T hi                : 100
>
>asel rh td
Ch1 Quantity        : RH
RH lo               : 0
RH hi               : 100
Ch2 Quantity        : TD
T lo                : -40
T hi                : 60
>
>asel t td 0 60 -20 60
Ch1 Quantity        : T
T lo                : 0
T hi                : 60
Ch2 Quantity        : TD
Td lo               : -20
Td hi               : 60
>
>asel rh none
Ch1 Quantity        : RH
RH lo               : 0
RH hi               : 100
Ch2 Quantity        : NONE
>
>asel none none
Ch1 Quantity        : NONE
Ch2 Quantity        : NONE

Table 4. ATEST command
Syntax Description
atest [val1 val2]<cr>
where
val1 val2
Analog channel output value (V)

Use the atest command to test the analog outputs. The atest command will force the output to the given value, which can then be measured with a calibrated multimeter.

The atest command affects only the analog outputs and hence it does not disable measurement functions. atest without parameters will exit the test mode and let the measurement continue. It will also indicate the current analog output levels in normal measurement state
Examples:
>atest
CH1: 2.360000
CH2: 3.765010
>
>atest 5.0 5.0
CH1: 5.000000
CH2: 5.000000
>
1 Measurement parameters are referred to as 'quantities' in the transmitter's software.
