Rolling Graph
If the Rolling Graph function is enabled, the display in basic User Mode shows the instantaneous
reading together with a real-time plot of immediate past readings in a 2-minute window. Enable the
rolling graph as with any other list selection menu.
Real Time Data
Real time data output to a PC is available via a USB cable and/or wirelessly via Bluetooth Low
Energy (BLE) using an Android App. Select ‘On’ in this menu and see Computer Interface section
below for procedures.
Language
The display language can be selected as English or Chinese. Chose the
language as for any other list selection menu.
Self-Zeroing
With Self-Zeroing enabled, the instrument re-zeroes automatically if the
signal drifts below the last Zero Calibration for some time. Such drift can
occur 1) slowly as the lamp ages, 2) a dust or oil film accumulates on the
lamp window, or 3) a change in environmental conditions such as
background matrix gas, humidity or temperature. The default setting of
self-zeroing is off. At the time of enabling self-zeroing, make sure the
instrument is running in clear environment for several minutes to ensure that
the baseline zero signal is well established. Enable this function as with any
other list selection menu.
Wireless
Wireless radio communication can be enabled if the instrument has a wireless module installed.
Enable this function as with any other list selection menu.
