Operation
Refer to the keypad diagram to identify the keys.
Connect the ADM-1000 to the head using the supplied cable, and switch the unit on
by holding the ‘I’ button at the top of the keypad until the unit beeps. The unit sets
itself to the last used settings.
If a photodiode head is connected, the wavelength of incident radiation will need to
be entered to get the correct reading. See the section ‘Wavelength’ below.
Display Mode
To switch between digital and graphical display modes, press the Display Mode
button. The last used settings are used in each mode.
Range
To set the full scale range, press the up arrow (8) to increase sensitivity or down
arrow (2) to reduce it.
Alternatively press Menu, scroll down to Range using the up arrow (8) or down arrow
(2) buttons, press Enter (green tick), scroll down the list and press Enter to select the
desired range or Cancel (red ‘X’) to revert to the original display.
Note that the range setting on the digital display is independent of the range set on
the graphical display, and more ranges may be available on the graphical display.
Auto-Range
The ADM-1000 has an auto-range capability in the digital display mode. In this
mode, the meter will automatically switch to a higher (less sensitive) range when the
measurement exceeds the present range.
Similarly the meter will switch to a more sensitive range when the measurement is
less than about 9% of full scale.
To turn on the auto-range function, press Menu, scroll down to Range, press Enter,
select AUTO and press Enter.
To turn off the auto-range function, press Menu, scroll down to Range, press Enter,
scroll down to select the desired range and press Enter.
