EM2-RDU Sample Rate vs. Storage Time
Sample Rate StorageTime hh:mm:ss
4 samples/sec 00: 20: 50
2 samples/sec 00: 41: 40
1 samples/sec 01: 23: 20
2 seconds/sample 02: 46: 40
4 seconds/sample 05: 33: 20
8 seconds/sample 11: 06: 40
On connection to Emeter II, RDU will upload
saved logs to Emeter and clear RDU memory
2 samples/sec is default setting
*Note that the max currents listed above are highly dependant on ambient air temperature, and especially the amount of
cooling airflow that passes through the RDU. On a cold day with good airflow, you may increase Continuous and 30-sec Max
amperages by some percentage, or reduce for hot days and poor airflow. Currents above 150A require user modification to
increase input/output wire size, and appropriate connectors. The “bottom line” is that it is your responsibility to check
temperatures to insure the RDU is not heat damaged (75C max). RDU unit returned with clear evidence of over-current heat
damage will NOT be covered by warranty replacement policy.

Also see http://media.hyperion.hk/dn/em2 (bottom of page) for the “Emeter II Suite” PC Software, which allows direct
programming of RDU parameters, log file downloads from SD Card or direct from the RDU, and “live” bench testing with RDU
connected to PC. The Suite also contains graphing functions, and will soon support other features such as test profile
creation for upload to the Emeter.
WARRANTY
- Emeter and RDU are guaranteed to be free from defects in materials and workmanship for a period of one calendar year
from date of purchase.
- Damage due physical shock (dropping on the floor, etc), inappropriate power supply (battery charger, etc!), water,
moisture, over-voltage or over-current operation, and humidity are specifically NOT covered by warranty.
- Your selling dealer is your first point of contact for warranty issues.
- Return postage costs are the responsibility of the user in all cases. Submit copy of original receipt with the return.
- Returned units should be examined by the Hyperion dealer’s tech department within 1 week of arrival, maximum, and
contact made with the user to explain the findings.
REPAIR/REPLACEMENT DUE TO NON-WARRANTY ISSUES:
Due to the nature of the miniature electronics employed, and high cost of hand labor and shipping involved, it is not
economically feasible to repair electronics in many cases. Instead, we offer a blanket exchange policy at 55% of the US$
original suggested retail price (plus any taxes due in your area, and return shipping). In the event that your Emeter/RDU is
user damaged and warranty will not apply, please contact your selling dealer to obtain the correct return shipping address,
for exchange under this program.
Best regards from the Hyperion Team, tech@hyperion.hk
