TESTS 
4-1. 
INTRODUCTION 
4-2. 
The 
procedures in  this section test 
the 
electri-
cal  performance 
of 
the 
Power 
Meter  using 
the 
specifications 
of 
Table  1-1 
as 
performance 
stand-
ards.  All  tests can be performed without access 
to 
the 
interior 
of 
the 
instrument.  A  simpler 
opera-
tional 
test 
is 
included in Section 
III 
under 
Opera-
tor's 
Checks. 
4-3. 
EQUIPMENT REQUIRED 
4-4. 
Equipment 
required for 
the 
performance tests 
is  listed  in Table  1-2,  Recommended  Test 
Equip-
ment. 
Any 
equipment 
that 
satisfies 
the 
critical 
specifications given  in 
the 
table may be substituted 
for 
the 
recommended model(s).

TEST RECORD 
4-6.  Results 
of 
the 
performance  tests  may  be 
tabulated 
on 
the 
Test Record 
at 
the 
end 
of 
the 
test 
procedures. The Test Record lists 
all 
of 
the tested 
specifications  and  their  acceptable  limits.  Test 
results recorded 
at 
incoming inspection can be used 
for  comparison in  periodic  maintenance, 
trouble-
shooting, 
and 
after repairs or adjustments. 
4-7.  PERFORMANCE TESTS 
4-8.  The performance tests given in this section are 
suitable  for  incoming inspection, troubleshooting, 
or 
preventive  maintenance.  During  any 
per-
formance test, 
all 
shields and  connecting hardware 
must 
be  in  place.  The tests are designed 
to 
verify 
published  instrument  specifications.  Perform 
the 
tests in  the order given  and record the 
data 
on 
the 
test card and/or in 
the 
data spaces provided 
at 
the 
end 
of 
each procedure. 
NOTE 
The 
Power 
Meter 
must 
have  a  half-hour 
warmup  and  the  line  voltage 
must 
be 
within 
+5%, 
-10% 
of 
nominal 
if 
the 
performance  tests 
are 
to  be  considered 
valid. 
4-9.  Each test 
is 
arranged so 
that 
the 
specification 
is  written  as 
it 
appears  in  Table  1-1.  Next,  a 
description 
of 
the 
test 
and any special instructions 
or 
problem  areas  are  included.  Each  test 
that 
requires test equipment has a setup drawing and a 
list 
of 
the 
required equipment. The initial steps 
of 
each  procedure  give  control settings  required  for 
that 
particular test.
