INSTANTANEOUS READINGS
(and Tacho Setup)
Function Screen/Mode
Cables/Wiring
2.1
Tacho - configure Optical Tach
READINGS>TACHO>push ‘C’ > CONFIG TACHO
None
Set Tacho Source as Emeter by pressing ‘B’ or ‘C’. Press ‘D’ and set blades as 1 to 6.
Without the RDU connected, the source will be set to Emeter automatically.
-- Set Tacho averaging:
On
averages rpm over 2 secs if < 9,000 rpm. Averages rpm over 1 sec if > 9,000 rpm
Off
averages over 1 sec always. Press ‘A’ to save tacho configuration
2.2
Tacho: configure Phase Sen.
Tach
READINGS>TACHO>push ‘C’ > CONFIG TACHO
*The RDU Tacho is for brushless motors and ESC only *
RDU + RDU cable +
Phase Tach
With the Emeter II, RDU and the phase sensor pick-up lead connected, the source can be selected as either
•
Emeter II for the optical tacho or
•
RDU for the phase sensor tacho
For RDU, the number of Motor Magnets must be set or erroneous results will occur. Set Gearbox ratio (“1” for direct drive)
2.3
Determine Motor Magnet Count
READINGS>TACHO push ‘C’ > CONFIG TACHO
RDU + RDU cable +
Phase Tach
Run the motor at steady speed with Emeter II close to spinning prop.
Vary no. of magnets until the RDU and Emeter II Opto rpm figures match and Save configuration.
2.4
Tacho - Read RPM optical
READINGS>TACHO
None
Hold top of Emeter II about 10 cm from rotating prop. Wait until readings steady. Avoid fluorescent lights
Press ‘D’ to hold reading (see sect 4.1). Press ‘C’ to save reading to SNAPSHOT 1-8 (see section 4.3)
Press ‘B’ to set prop constants, if known and show motor output power (see section 5)
2.5
Tacho – Read phase sensor RPM
READINGS>TACHO or
READINGS>ANALYSER
RDU + RDU cable
+ rpm sensor cable
Connect rpm sensor lead to RDU RPM socket and to any of the 3 wires of brushless motor. * Do not use on brushed motors *
2.6
Read Volts Bench-Test
READINGS>ANALYSER
RDU + RDU cable
0 to 70 volts, 2 dec. places
2.7
Read Amps Bench-Test
READINGS>ANALYSER
RDU + RDU cable
0 to 150 amps peak, 1 dec. place. BATTERY shows voltage, max. and min. and ma-h energy input and output (charge &
discharge)
2.8
Watts into ESC/Motor
READINGS>ANALYSER
RDU + RDU cable
0 - 10000 watts, calculated as the product of Volts * Amps
2.9
Motor/ESC Efficiency
READINGS>ANALYSER
RDU + RDU cable
Displays efficiency if Prop Constants in place and less than 100%. Press ‘D’ to hold values on screen. Press ‘C’ to save values
in SNAPSHOT 1–8
2.10
Motor Output Power & Thrust
READINGS>TACHO
None
Display power in Watts and BHP and thrust in grams if propeller constants exist for the given prop.
2.11
Height
READINGS>ANALYSER
RDU + RDU cable
The height sensor is fitted in the RDU and is set to zero metres when power is connected to the RDU. Position in model may
affect readings. See Emeter II manual for more.
