Record Readings in Memory Groups

The CG304 offers 50 memory storage groups, Group ‘0’ through ‘50’.

Group ‘0’ does not allow data to be stored; it is simply a group that can be selected if readings are

to be taken without being stored.

Use the UP/DOWN arrow keys to scroll to a particular group. When a reading is taken it is

automatically stored in the selected group (except if Group ‘0’ is selected). Each Group can store

up to 50 readings (for a total of 2500 for the 50 groups).

To delete all groups, or an individual group, use the MEASURE VIEW mode as explained in the

programming menu section of this User Guide.

In GROUP mode, if the storage capacity is exceeded. The meter’s display will show ‘Data Full’.

Bluetooth®

This meter has the capability to connect to and communicate with a PC via Bluetooth. To transfer

data, enter the SET Menu and switch on Bluetooth as explained below and the Programming

Menu section earlier in this guide. Measurement data will be sent automatically by way of the

Bluetooth utility.

Select ENABLE or DISABLE under Bluetooth in the SET Menu using the arrow buttons. If disable is

selected the Bluetooth will be completely disabled. When Bluetooth is enabled data will be

automatically sent to PC, phone, or other Bluetooth receiving device.

When the first connection is made the device may prompt for a PIN number. In this case enter

code 0000.

Note: Use Bluetooth only when necessary as the battery will drain more quickly with Bluetooth

powered ON.

Check the software download page of the website www.extech.com for the latest version of the

PC software and its operating system compatibility.
