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 Pyroelectric 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 PYRO
(down) position. A 3 meter BNC type cable comes with Vector pyroelectric detectors. Connect the cable to the
indicator’s BNC connector.
5. To Configure the H410 for a Pyroelectric Detector:
Note: Some of the menu selections are skipped in this section. They are discussed in detail in
later sections.
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.
The operating parameters for the pyroelectric detector you are going to use must be entered into the H410’s
memory. First the output sensitivity of the detector’s crystal is entered, then the speed, based of the detector’s
type of absorbing surface is entered.
To enter into the configuration mode:
A. Press the MODE button. A menu cycle of J, AVG J, W, CAL and tO will begin.
B. Press the ON/SELECT button when “CAL” appears. A menu cycle of CAL 1, CAL 2, Attn and SPd
will begin.
C. Press the ON/SELECT button when “CAL 1” appears. The current V/J output sensitivity will be
displayed and the “SET CAL” annunciator will flash.
D. Use the RANGE (count up) button to increase the value or the MODE (count down) to decrease the
value to enter the V/J value listed on the pyroelectric detector’s serial tag.
E. Press the ON/SELECT button to exit this menu. The indicator will return to the last operational state.
F. Press the MODE button to return to the menu in step A.
G. Press the ON/SELECT button when “CAL” appears. A menu cycle of CAL 1, CAL 2, Attn and SPd
will begin.
