Page 13: 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 14: Operation
Refer to the keypad diagram 1 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. -
Page 15: Auto-Range
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. -
Page 16: Peak/Average Measurement
Peak/Average Measurement There are two types of measurement mode that can be selected for the digital display- Average or Peak. In average measurement mode, the measured signal is averaged over a period set by the user and will give a useful average (mean) value for steady (CW) sources or pulse periods which are less than the user-set average time period. -
Page 17: 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 the menu button, scroll down to Zero, press The options Set and Clear are presented. -
Page 18: Display Contrast

Page 24: Normal Mode
Normal Mode In Normal mode, if no valid triggers occur the waveform is not updated and ‘No trig’ is shown at the top of the display. The last waveform that triggered the instrument is kept on the screen until the signal next crosses the trigger level in the specified direction. -
Page 25: Cursor Function
Cursor Function The ADM-1000 has a cursor function which enables various measurements and 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 at the leftmost side of the screen, one of which is flashing. - Page 26 ∆ P (Delta-P) Power difference between the cursors. This is used for measuring pulse amplitudes or amplitude differences. 1/∆t (Frequency) This is used to measure frequency (PRF) in Hertz. The display should if possible be arranged so that two pulses can be seen, and the cursors should then be set to the same point on each of the two adjacent pulses.
- Page 27 Pulse Energy The total energy between the cursors, in Joules. For pulse energy, the display is arranged to show one pulse as large as possible, and the cursors set one either side of the pulse. The energy in the pulse is displayed. The total energy between any two points can also be shown.
