SETUP
1. Choose the power source.
Before using the DPH230SD, be sure it is powered by fresh
batteries or an optional 9VDC AC adapter plugged into the bottom jack on its right side
(callout 1-15).
To remove the battery compartment cover, remove the two screws holding it in place
(callout 1-11). Then install six “AA” batteries in the correct orientation, using the polarity
marks on the inside of the compartment as a guide. Replace the cover by replacing the two
screws.
2. Install an SD card.
To prepare for setup, also install the supplied 2 GB SD memory card
or another card with a capacity from 1 GB to 16 GB in the socket on the bottom of the
DPH230SD (callout 1-18). When installing the card, make sure its gold contacts are
facing front and push the card into the socket until you hear a click. To remove the card,
push it in until you hear a click and the card pops out.
Now power on the instrument by pressing the POWER button (callout 1-2) to generate a
short beep. (To power off the DPH230SD, press the POWER button and hold it until the
instrument responds with a long beep.)
When the meter powers on, a series of transient startup screens will briefly appear. Once
the display has stabilized, perform the following eight setup steps in the order presented.
3. Format the SD card.
LOGGER SET button (callout 1-8) and hold it for at least five
seconds, until “Sd-F” appears in the lower half of the display. Quickly (within three
seconds) press the REC/ENTER button.
(If you press buttons too slowly in setup mode, the screen will revert to the normal display.
To return to the setup sequence, press and hold the LOGGER SET button again. To move
ahead to the next field in the sequence or to the next parameter, press the HOLD/ESC
button.)
Pressing the REC/ENTER button causes the word “no” or “yES” to appear over the term
“Sd-F”. Press the
▼
button to make a selection. Choose “yES” whenever a new SD card is
being used, or when a used card is being repurposed (from use with another SD card
instrument or a camera, for example) and all data on it is to be erased. Choose “no” to
preserve any data on a card previously used with this instrument.
