4.6.2 Meas

The Meas menu of the 66203/66204 Digital Power Meter has Shunt, Meas, Integ, Filt, Disp,
Hold, THD, Inrush, Energy, CT, ExtenSH, HV, EFF total 13 functions that are described
below.

SHUNT

Figure 4-34 Setup Screen of SHUNT

The 66203/66204 Digital Power Meter offers two internal shunts for current sensing which
are 5m

Ω

(High shunt) and 500m

Ω

(Low shunt). The measurement ranges of High shunt are

20Arms/5Arms/2Arms/0.5Arms while Low shunt measurement ranges are 0.2Arms/0.05Arms
/0.02Arms/0.005Arms.    The Digital Power Meter has AUTO, High, and Low three types of
shunt for selection.

Following is the procedure to set the range:

1. Press

SETUP

and select Meas. The Meas indicator is on indicating it is in Meas menu.

2. Use

↑

,

↓

to select SHUNT function in the 1

st

display window and press

TRIG/ENTER

to

confirm the selection.

3. Before setting any parameters, press

CH-SEL

to select the desired channel for testing.
