Be sure the photodiode detector is appropriate for the laser measurements you plan to make. Please familiarize
yourself with the detector’s operation specifications before you use it.
Note: Photodiode detectors can only be used to measure continuous wave lasers.
1. To Turn On the Meter:
Note: For the most accurate measurements possible, the H410 should be turned on and warmed
up for 30 minutes.
Slide the ON/OFF switch, located on the upper right side of the H410, to the ON position. The indicator will
immediately turn on in the operational state last used. If you purchased the H410 with one detector, this
detector’s operating parameters will be in the indicator’s memory and you are ready to take measurements.
If you purchased more than one detector with the H410, you must make sure the operating parameters for the
detector you plan to use are in the indicator’s memory. For detailed instructions please refer to the operating
parameters listed on page 2 and the following procedure.
2. Turn the Analog Needle On or Off (does not apply to the H410D):
To turn the analog meter on or off, press and keep holding down the ON/SELECT button. Then release the
button after the meter appears or disappears.
3. Zero the Analog Needle (does not apply to the H410D):
Refer to Figure 2. The black slotted button located just below the display allows screwdriver adjustment to set
the analog needle to zero. This adjustment should be made before connecting the detector.
4. To Connect a Photodiode Detector:
Note: Only one detector should be plugged in at any time.
Refer to Figure 2. Slide the CAL/PYRO switch, located on the upper left side of the H410, to the CAL (up)
position. A 3 meter mini DIN type cable comes with Astral photodiode detectors. Connect the cable to the
indicator’s mini DIN connector.
5. To Configure the H410 for a Photodiode Detector:
Note: You must save all settings by pressing and holding the OFF/CANCEL button until the
display blanks. If the H410 is turned off, by using the ON/OFF slide switch, before settings
are saved they will be lost.
To enter into the configuration mode:
A. Press the MODE button. A menu cycle of W, CAL and Attn will begin.
B. Press the ON/SELECT button when W appears. A menu cycle of U and UIS will begin. Choose U
(ultraviolet) for the model AP30UV or UIS (visible) for the model AP30.
C. Press the ON/SELECT button when the appropriate option is in the display. The H410 is now
configured for the chosen photodiode detector and will return to the last operational state.
D. Press and hold the OFF/CANCEL until the display blanks to save the setting.
E. Press the ON/SELECT button to turn the H410 back on.
