5.7.3 Setting up the mA output parameters
☞
If auto ranging is selected, the way in which the output changes between the
ranges depends on the values you have set for the range change point and
the hysteresis.
For example, if you set the range change point to 18% and set hysteresis to 1%, then:
•
The output value must be greater than 18% before changing from range 1 to
range 2.
•
The output value must be less than 18% – 1% (17%) before changing from range 2
to range 1.
Use the following procedure to select auto ranging or manually select the range:
1.
Select
➞
Set up
➞
mA output.
2.
Select the required measurement
range option.

screen (one measurement analyser)
3.
Select the range option you want the
output to use (range 1, range 2 or
auto). If you have selected auto
ranging, you must also set the range
change and hysteresis values.

Return to the mA configuration
screen (Figure 48) and select 'Set up'
option.
5.
Edit the range high level and low
level.
