SERVO TESTER

Servo testers

are

very useful

for

exercising your servos

and

Electronic

Speed Control

(ESC)

without

the

need

to

turn

on

your transmitter,

and

you

do not

even need your receiver.

The

servo tester will

put out a

signal just like

the

signals normally sent

by

your receiver

to the

servos

or

ESC. The

dial knob

on the

servo tester will change

the

signal just

like moving your transmitter stick would change

the

signal going

to a

servo

or ESC.

To use the tester to evaluate a servo

Connecting

a

battery

to the

i-Meter

volt port. Plug

a

servo into

the

servo port.

The

servo

can be

controlled with

the

adjustment dial under

Manual Mode. Press 'MODE' button once

to set the PPM

signal

to

auto.

The servo tester will

use

1520us

as

centre

and

automatically output

cycling signal

to

move

the

servo

arm

back

and

forward.

To use the Servo Tester to operate an ESC and motor

Connecting

a

battery

to the

Mega Meter volt port. Another plug connec-

ted

to the

Servo Tester

is the

plug from

the ESC

that normally goes

to

the receiver. Connect

the ESC to

motor leads. When

you

connect

the

battery

to the ESC it

will power

up. It

should react

the

same

way

does when powered

up

using

the

radio gear with

the

throttle stick

in

the minimum power position.

You can now

spin

up the

motor

by

turning

the servo tester knob.

No

receiver

or

transmitter

is

needed. This

is a

great

way to

test motors

on the

bench.

TACHEOMETER

RPM

There

is an

optical tachometer within Mega Meter.

An

optical tacho

sensor

is

fitted

to the

right side Mega Meter case

and is

activated

by

pointing Mega Meter towards

the

propeller

at a

distance

of 10 and

20cm

from

the

propeller.

The fluctuating light caused

which

is

being measured

and

so

the

gear ratio

is not

really relevant.
