HF scientific AccUView UV %Transmission Monitor - Manual (Page 17)

Since the instrument stored the reading previous to calibration, this reading will appear
after calibration for at least 30 seconds. The reading will then update to the current
reading. How fast this upgrades occurs depends on the CONFIG settings for RESP
(response time) and UV-T ( lamp duty cycle).
Note: It is recommended that the flow through unit be removed for as short an interval as
possible to prevent premature saturation of the desiccant.
Warning: While the UV lamp is of very low power, do not look directly into the
optical well while the flow through unit is removed.
5.2 100%T Calibration Error
If the screen shown below is displayed after the 100%T calibration, the internal
diagnostics have determined that the calibration fluid requires replacement or the flow
through cuvette requires replacement. Check, the calibration fluid & cuvette, then
recalibrate or restore the factory calibration see 6.1 Restoring Factory Settings. The
instrument cannot be used without performing one of these operations.
To recalibrate press the MODE key and start the calibration sequence again. To restore the
factory calibration, push and hold the
tbutton. Now push and release the ↵ then release
the
tbutton.
