Power Meter Operation

Making Measurements using Sensor Calibration Tables

A calibration factor in the range of 1% to 150% can be entered.

 

The following rules apply to naming sensor calibration tables:

 

■ The name must consist of no more than 12 characters.

 

 

 

■ All characters must be upper or lower case alphabetic

 

 

 

 

characters, or numeric (0-9), or an underscore (_).

 

 

 

 

 

 

 

 

■ No other characters are allowed.

 

 

 

 

 

 

 

 

■ No spaces are allowed in the name.

 

 

 

 

 

 

 

 

2. To edit the parameter you currently have selected press

 

 

 

 

.

 

Change

 

The power meter displays the data in a pop up window. Modify

 

this data (see below) as desired.

 

 

 

 

 

 

 

 

■

Use

or

to modify the character on which the cursor

 

 

is currently positioned.

 

 

 

 

 

 

 

 

■

Use

or

to move to other characters.

 

 

 

 

 

 

 

 

3. To confirm your choice press the appropriate softkey.

 

 

 

 

 

 

 

 

4. To add a new sensor calibration table entry press

 

 

 

. You are

 

Insert

 

prompted for the frequency and calibration factor. The entry is

 

sorted by frequency.

 

 

 

 

 

 

 

 

 

 

 

 

5. To remove a sensor calibration table entry use the

,

 

 

 

 

,

 

 

 

and

hardkeys to select the entry, press

 

 

 

. If you

 

 

 

 

 

 

 

Delete

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

delete the frequency the equivalent calibration factor is also

 

 

 

removed and vice versa.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Note

You can only edit the table name you cannot delete it.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

6. When you have completed editing the sensor calibration table

 

press

 

to return to the “Sensor Tables” screen.

 

 

 

 

 

 

 

 

Done

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Note

Ensure that the frequency points you use cover the frequency

 

 

 

range of the signals you want to measure. If you measure a signal

 

with a frequency outside the frequency range defined in the sensor

 

calibration table, the power meter uses the highest or lowest

 

 

 

frequency point in the sensor calibration table to calculate the

 

 

 

calibration factor.
