2.4.1 Battery Installation/Replacement
The Model 1815-C uses a 3.5 digit announciated LCD display. The display’s
BAT announciator lights when the battery voltage has dropped to 7 volts and
indicates that new batteries are needed. The Model 1815-C uses six 1.5V AA
batteries. To replace these batteries use the following procedure:
1. Turn the Model 1815-C off and open the case by removing the two
screws on the bottom of the meter.
2. Unfasten the velcro straps, and remove the batteries.
3. Insert six new 1.5V AA batteries (Alkaline) making sure to orient the
polarity of the batteries as indicated by the battery holders.
4. Secure the velcro across batteries.
5. Close and resecure the case with the two screws.
2.4.2 Power Up
Turn on the Model 1815-C by depressing the POWER switch located on the
front of the meter. The digital display should light indicating that the meter is
operating. If the BAT announciator is lit, replace the batteries. See Section
2.4.1.
2.4.3 Detector Connection and Setup
Connect the detector to the INPUT BNC found on the rear of the Model 1815-C.
You may connect or disconnect any Newport Low-Power, or High-Power
detector at any time (even when the meter is on) without damage.
Adjust the SETUP switch bank to reflect the type of Newport detector that the
Model 1815-C is being used with. If you are not using a Newport detector,
follow the table below when setting up the Model 1815-C. This table is repro-
duced on the rear panel of the Model 1815-C, see Figure 3.
