Emeter v2 Quick Guide 2.09

Introduction  

The Hyperion Emeter II can carry out an enormous range of functions related to Electric Powered models and 

small vehicles, and has been designed with ease of use as a prime objective. On-screen help, a menu system 
and friendly error messages all contribute to this objective while in the field or at the lab. 

 

This Quick Guide describes the scope of Emeter II and how to make it work for you, in a sequence which 

matches the on-screen menus. The Emeter’s own On-screen help is a subset of this information intended to 
answer most questions at the field. The full Emeter II User Manual (Download from link above) goes into 

greater depth with explanations of many of the issues surrounding Electric Power and Radio Control models. 

 
The Emeter II System consists of two major components:  

 

The pocket sized case houses the display screen, an SD Card slot, buttons for menu navigation, a 

potentiometer to drive pulse-width devices such as servos and motor controllers, an optical tachometer, 
and an internal battery pack with onboard charger. 

 

 A Remote Data Unit which, with its small size can be fitted to the power system (RC model, robot, 

scooter, etc…) to log data. At the end of the logging period, the captured data can be copied to the 

Emeter II for display, without the need for a Personal Computer.  
 

In addition, the Emeter v2 comes with two cables in the box:

 

  --  A 

Data Cable

 (aka “RDU Cable”, #HP-EM2-4PINCBL). It has a locking Molex 4-pin connector on one side 

which fits the Emeter v2 at bottom-right port.  The other side has 5-pin female connector (with one pin 

“blanked”).  This side fits the RDU so that the RDU can transfer files to Emeter, and communicate during Bench 

testing or RDU setup.  The same side also fits Hyperion TITAN series ESC, for programming via Emeter. 
  --  A 

Power Cable

 (#HP-EM2-PWRCBL) with 4.5mm plug on one side, and tinned wires on the other.  The 

Emeter contains a 5-cell 750mAh NiMH battery inside, and an INTERNAL CHARGER.  You should never connect 

a battery charger to this power input.  Instead, simply use any 12V~15V DC power supply with 120mA or 

higher capacity (such as a 13.8V DC power supply, Automotive battery, or discarded 12V “Wall PS” from some 
old toy, router, etc).  

Please take time now

 to fit appropriate connectors to this cable, and plug in your 

Emeter to a 12-15V power source for charging.  See details below for charge rate and time. 

 

Terminology 

RDU 

– The 

R

emote 

D

ata 

U

nit contains data storage, and sensors for measuring voltage, current, height 

(altitude from start point), ambient temperature and other data. In addition the RDU has input/output 

connectivity to a receiver or pulse-width driver such that throttle position can be recorded or remote on/off of 

logging controlled.  The RDU can record peak currents up to 150A with stock wiring (up to 300A, 5 sec, 
modified), with a maximum of 70V input.  There are also optional sensors available for up to three external 

temperatures and phase tachometer for brushless motors at this time, with other sensors planned for 2009. 

 
Before using the RDU, it is necessary to solder on the connectors of your choice to the RED/BLACK wires 

marked INPUT (Battery, DC PS) and LOAD (Motor, Charger, Discharger, etc) on RDU bottom.  The connectors 

must be high-quality and matched in size to the maximum currents you expect to draw.  Although the RDU is 
protected against accidental connection with polarity reversed, the ESC which is normally connected to the 

LOAD side of the RDU, is likely not protected and will be destroyed by reversed polarity. So take great care with 

connector polarity. 

 

ESC

 - Electronic Speed Controller is used to vary the speed of the model’s motors 

 

BEC

 - Battery Eliminator Circuitry, optionally included in the ESC, is used to power receiver/servos from main 

power pack instead of a separate receiver pack 

 

SD Card

 – is a mass data storage device which may also be used for transfer of data between a PC and the 

Emeter II, including: 

 

Emeter II and RDU firmware updates 

 

Files for On-line screen help  

 

Prop constants data 

 

Data logs  

 

Parameters for user-programmable servo or ESC drivers 

 

An SD card is not included but is strongly suggested for complete functionality.  Standard (or Mini/Micro in adapter) SD SDHC 
cards up to 4Gb are supported.  They must be formatted as FAT16 or FAT32.  

 

Phase Tachometer

 sensor – (option part #

 

HP-EM2-TACHBL) has a single wire which should be connected to 

any of the three wires into a brushless motor, and the 3 pin plug which fits the RDU socket labelled ‘RPM’. 
 

External Temp 1,2,3

 sensors – (option parts #HP-EM2-TMP1 and #HP-EM2-TMP23) Note that Temp#1 must 

be purchased in order to add temps #2 and #3, as only TEMP#1 connects direct to RDU (2,3 connect via #1).
