| Note: |
|
[1]If the tester is not going to be used, or is being stored for a
long period, remove the battery and store separately from the tester to
avoid
damage from battery leakage. |
|
| Note: |
|
[2]The four temperature ranges for the tester exists to satisfy
European Standards requirements; the instrument can be used over the
full
working temperature range by using the temperature coefficient to
calculate accuracy at the ambient temperature of use. |
