Select Units

Use the UNIT command to select metric or non-metric output units.

Only affects data shown on the display and service port, has no effect on

the analog and digital outputs. This command is not available on the

digital output models (for example, HMW95).

UNIT [x]<cr>

where

Selects the unit type to output:

m = metric units, for example, Celsius

n = non-metric units, for example, Fahrenheit

Example:

>unit m

Unit : Metric

Analog Output Settings

NOTE

Commands for configuring analog outputs are not available on digital

output models (for example, HMW95).

Set Analog Output Mode

Use the AMODE command to set the analog output mode and error

level. Note that you cannot change between analog output types, for

example, from voltage to current output.

AMODE [channel lo_value hi_value error_value]<cr>

where

channel

Analog output channel, 1 or 2.

lo_value

Low limit of the channel.

hi_value

High limit of the channel.

error_value

Error value of the channel.

Example (show current configuration):

>pass 9000

>amode

Aout 1 range ( V) : 0.00 ... 5.00 (error: 5.50)

Aout 2 range ( V) : 0.00 ... 5.00 (error: 5.50)

Example (set channel 1 to 0 ... 1 V output, with error level at 2 V):

>amode 1 0 1 2

Aout 1 range ( V) : 0.00 ... 1.00 (error: 2.00)

1 2 ... 44 45 46 47 48 49 50 51 52 53 54 ... 109 110
