Lamp (Lmp) Submenu:
If the instrument measurements are excessively noisy (with a standard deviation above 2 ppb) or are
always near zero in the presence of ozone, it is useful to perform a UV lamp check. Before performing
the test, allow the instrument to warm up for 30 minutes.
From the instrument menu, select
Lmp
and push the
Function
Knob. The display will momentarily
read:
Lamp Test
The diagnostic results will then be displayed after a short delay, for example:
PDV= 0.89801 V
1.2 +/- 4.85
The PDV value should be in the range: 0.6 to 2.2 V and the +/- value should be less than 2.5. If either
of these values are out of range, please contact our Technical Support.
Digital Data Output
The UV-100 may be connected to a computer (via USB or serial cable) to transmit real-time data or
internally logged data. 3
rd
-party terminal programs such as TeraTerm or puTTY are available online for
interfacing with the UV-100. These programs should be setup for serial communication with the UV-100
on the correct COM port with the following settings:
Baud rate: 9600
Data Bits: 8
Parity: None
Stop Bits: 1
When the UV-100 is connected to a computer with these settings, the instrument will output a line of
data at the rate defined by the averaging setting (
Menu > Avg
).
When the instrument is not in logging mode, the data output will be in the following form:
0.00,304.7,739.6,731,1.057,07/03/16,15:14:39
0.00,304.7,739.6,745,1.059,07/03/16,15:14:49
