Specification
This is particularly useful in diagnostic testing of
circuits where nuisance tripping is a problem and helps
to identify the difference between an over sensitive RCD
and excessive leakage from poor insulation or
equipment with high leakage.
Use the rotary switch to select the rating of the RCD.
Press the RCD multiplier button until the symbol is
displayed.
Press the test button to start the test. The fault current
applied will increment in 3mA steps until the RCD trips.
If nuisance tripping on a circuit is a problem this function can be used to retest the RCD with
other appliances systematically connected and removed.
For example a 30mA RCD may trip at 12mA on ramp test with an appliance connected and
then at 27mA with the appliance removed. You will know that the appliance is leaking
approximately 15mA.

Principle of Measurement
During phase rotation measurement the amplitudes and phase angles of the three inputs L1 L2
L3 are checked against limits, allowing for mild unbalance conditions.The indication 1-2-3 is
displayed for normal rotation (L2 lags L1) and 3-2-1 for reverse rotation (L2 leads L1).
Display of Phase rotation is Automatic when all three tests leads are connected to the 3 phase
supply as below:
Set the main rotary switch phase
Using three test leads, connect test leads to the L1 to Phase 1, L2 to Phase 2 and L3 to Phase
The Ethos 8400 will display .1 .2 .3 or .1 .3 .2 depending on the direction of phase rotation.
WARNING
Only use LR6 Alkaline replacement batteries.
Please dispose of your batteries carefully.
Batteries are made from important resources and chemicals, including lead, cadmium, zinc,
lithium and mercury. If batteries are disposed of as normal waste, they’ll be taken to a landfill
site and those resources will be lost and will contribute to the pollution of the environment.
Recycling is one way you can help the environment and you should dispose of used batteries
separately from other waste, using local collection
and recycling schemes available.
