PN 10795T 20
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 power
meter 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 power meter’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 power meter’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 1. 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 Calorimeter
Only one detector should be plugged in at any time. Refer to Figure 1. 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 Vector calorimeters. For large aperture calorimeters the interconnect cables for both the
calorimeter and the power meter are hard wired to the interface module. Connect the cable(s) to the
detector and the power meter’s mini DIN connector.
5. To Configure the H410 for a Calorimeter
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 calorimeter you are going to use must be entered into the H410’s
memory.
