Page 3: Introduction
A DC power supply is included with the ADM-1000. The lead is connected to the 6VDC socket on the end of the ADM-1000, the power supply is then plugged into the mains. The ADM-1000 will operate from the power supply regardless of whether the battery pack is fitted or not. -
Page 4: Usb
The ADM-1000 will typically run for 5 hours or more on a good, fully charged battery pack. A longer operating time will be achieved if the backlight is used less. -
Page 5: Switching On
To turn the unit off, press and hold the ‘O’ button at the top of the keypad until the unit turns off. If the ADM-1000 is connected to a USB port, unplug the USB lead to turn the unit off. Po wer Of f... -
Page 6: Display Mode Summary
Display Mode Summary The ADM-1000 can operate in digital (numerical) or graphical (waveform) display mode. Digital Display Features Manual or auto ranging numerical display. This display shows the measured value in numerals with units. A bargraph trend indicator beneath the digits shows the current value relative to the full scale on the selected range. -
Page 7: 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. -
Page 8: Wavelength
Note that auto-range facility is not provided in the graphical display mode. Wavelength Photodiode heads do not have a linear response and the wavelength of the incident radiation must be entered by the operator for meaningful measurements to be made. The wavelength response of each detector head is stored in the head at calibration and the correction factor is automatically applied once the wavelength has been entered. -
Page 9: Zero Offset
Zero Offset For accurate measurements it may be necessary to set the point at which zero light is displayed. This is achieved by blocking off all light to the detector and then zeroing the meter. To set the zero point, press menu, scroll down to zero, press enter. Message, “Set zero light level?”... -
Page 10: Graphical Mode Functions
Graphical Mode Functions In graphical display mode there are two modes which enable quick selection of the most commonly used commands. The mode is indicated by the label ‘RNG’ or ‘TRG’ in the bottom right corner of the display, and the mode can be switched between the two by pressing the ‘5’... -
Page 11: Start Acquisition
Start Acquisition To stop and start the acquisition, press the ACQ (0) button. If cursor calculations are enabled, the cursors and current calculation will be displayed when the acquisition is stopped. Rolling Display At slow timebases the trace will travel across the display until it reaches the right hand side, whereupon the waveform will start scrolling to the left as new data is added to the right (Stripchart mode). - Page 12 Ho rizon tal Trigg er P oint Tri gger Poin t: Po int a t wh ich t he in stru men t Trig Auto sta rted to c aptu re t he wav e f orm Ve rtica l Trig ger Le v el Th is pu lse occu rred 20 µs be fore th e m ain...

Page 14: Cursor Function
Cursor Function The ADM-1000 has a cursor function which enables various calculations to be made on displayed waveforms. In waveform display mode, press ACQ (0) to stop the acquisition. Two small crosses are displayed on the waveform, one of which is flashing. The meter can perform... -

Page 19: Connecting The Adm-1000 To A P.c
P.C. If the ADM-1000 is connected to a low power port such as a USB hub which has no power supply of it’s own, or a long USB lead is used, the meter will need batteries or a power adaptor.
