1. Overview
1.1 Product Introduction
This 66201/66202 Digital Power Meter manual covers the product model
of 66201 and 66202. 66201/66202 is a digital power meter with voltage
and current auto ranging function that can identify PASS / FAIL of UUT
based on the inputted specification. Its front panel has 4 sets of
7-segment LCDs that can display AC voltage, current and the
measurements of active power / power factor / apparent power / reactive
power concurrently. The valid measurement ranges are 0 ~ 500 Vrms
for AC voltage, 0 ~ 20Arms for AC current, 0 ~ 10KW for active power, 0 ~
1.000 for power factor, 0 ~ 10KVA for apparent power and 0 ~ 10KVAR
for reactive power.
66201/66202 Digital Power Meters can also connect to PC via GPIB
(IEEE standard 488-1978) and USB interfaces to perform measurements
automatically when on line.
1.2 Inspection
Before shipment, this instrument was inspected and found to be free of
mechanical and electrical defects. As soon as the instrument is
unpacked, inspect for any damage that may have occurred in transit.
Save all packing materials in case the instrument has to be returned. If
damage is found, please file claim with carrier immediately. Do not
return the instrument to Chroma without prior approval.

1.3 Ambient Environment
(1) Do not use the meter in a
dusty or vibrating location.
Do not expose it to sunlight
or corrosive gas. Be sure
that the ambient
temperature is 0°C ~ +40°C
and the relative humidity is
20% ~ 80%.
Keep away from the followings:
Dust
Direct Sunlight

Power Filter
Please install a po wer filter in
case of interference from high
power noise.
(2) The meter has been
carefully designed to
reduce the noise from the
AC power source.
However, it should be used
in a noise-free or as low as
possible environment. If
noise is inevitable, please
install a power filter.
(3) The meter should be stored
within the temperature
range -40°C ~ +85°C. If
the unit is not to be in use
for a long time, please
store it in the original or
similar package and keep it
from direct sunlight and
humidity to ensure its
accuracy when using
again.
1.4 Power Line Connection
Before plugging in the power cord, make sure the power switch is off and
the voltage selector on the rear panel meets the required voltage. Please
use the power supply frequency of 50Hz or 60Hz.

1.5 Fuse
There is one fuse installed in the rear panel, please be aware of the
following when replacing it:
(1) First turn off the power and unplug the power cord before changing
the fuse.
(2) Since visual check cannot ensure the fuse to be used is appropriate,
it is necessary to test its resistance to see if it is below 15Ωwhich is
normal when checking.
(3) When replacing the fuse, use a finger or a flat screwdriver to press
the cover of fuse holder gently and turn it counter clockwise for 60
degree, the cover will be unlocked from the holder for 3mm.
(4) Remove the over and replace the fuse with a new one (must be
same as the original fuse.)
(5) Press the cover down into the holder by a finger or a flat screwdriver
and turn it clockwise for 60 degree to secure it.

Power Fuse Slow blow 0.5A Applicable for AC 190V ∼250V
WARNING To prevent fire from occurring it is required to use the
fuse of same type and same specification when
replacing it.

1.6 Time for Warm-Up
All functions of this meter are active when it is powered on; however, to
meet the accuracy listed in the specification it is suggested to warm-up for
at least 60 minutes.
1.7 Cleaning
Ensure all cables and power cords are removed before cleaning the
hardware. Use a dry cloth to clean the chassis. As the rear panel of
power meter connects to the internal circuit board, to avoid damaging the
hardware due to short circuit internally it is not allowed to wipe it with
damp cloth.

3. Operation
3.1 Preparation before Test
(1) Before plugging in the power cord, make sure the power switch is off
and the voltage selector on the rear panel meets the required
voltage.
(2) If there is a need to change the voltage, ensure the fuse used
matches the voltage selected. See section 1.5 Fuse for the
specification.
WARNING It is required to remove the power cord when replacing
the fuse or changing the input voltage to avoid the
hazard of electric shock.

Digital Power Meter 66201/66202 Quick Start Guide
The connection of Figure 3-1(a) is more accurate for current
measurement; however, the voltage measurement may have small errors
due to the voltage difference of current meter. It is applicable for the
UUT with medium or small power. Its connection with 66201/66202
Power Meter is shown in Figure 3-2.
The connection of Figure 3-1(b) is more accurate for voltage
measurement, but the current measurement will add the leakage current
from voltage meter. It is applicable for the UUT with medium or larger
power. Its connection with 66201/66202 Power Meter is shown in Figure
3-3.
