116 Operating the Meter
To update the meter’s firmware …
1. Turn your meter on. Observe the firmware version
number, which is displayed briefly about three seconds
after you turn the meter on. The meter can be updated
if the firmware version is 3.0 or higher. Stop if the
firmware version is lower than 3.0 – these meters cannot
be updated in the field.
2. Establish communications between the meter and
your computer as described in Establishing
Communications... It is very important that you make
good connections at both ends of the cable used to
connect the meter to your computer.
3. Since stored data will be overwritten during the update
process, download any survey data that you want to
save by following the directions described under
Downloading Logged Data from the Meter.
4. Select Update Meter Firmware from the Update Meter
Firmware menu.
5. Read the directions and click OK to continue or click
Cancel to abort the update process.
6. Enter the password obtained from Narda and click OK.
7. Read the description of the three meter models. Click
Yes to update a Model 8718B meter. Click No if your
meter is a previously updated Model 8718 unit that
currently has firmware version 3.0 or higher. Click
Cancel if the meter is a Model 8718 that has a firmware
version lower than 3.0. These meters cannot be
updated in the field.
8. The update process begins when you click either Yes
or No as described above. Do not interrupt the update
process.
9. You should get a message box that the firmware has
been updated in about three minutes (at the
