28 II EX Calibration Manual Supplement
11/12 1
Change #1, 62942
On page 8, replace Duty Cycle (Vdc and mVdc) with:
Duty Cycle (Vdc and mVdc)
Range Accuracy
0.0 % to 99.9 % [1] Within (0.2 % per kHz + 0.1 %) for rise times <1 s. [2]
[1] 0.5 Hz to 200 kHz, pulse width >2 s. Pulse width range is determined by the frequency by the frequency of the signal.
[2] For 6 V dc range accuracy is unspecified.
Under MIN MAX Recording change:
From:
250 s (peak) [1]
Specified accuracy 100 counts for changes >250 s in duration
(add 100 counts for readings over 6000 counts)
(add 100 counts for readings in Low Pass mode)
To:
250 s (peak) [1]
Specified accuracy 200 counts for changes >250 s in duration
(add 100 counts for readings over 6000 counts)
(add 100 counts for readings in Low Pass mode)
On page 14, Step 19 replace the Range:
From: 6 V
To: 60 V
On page 15, Step 44 replace the UUT Measurements:
From
44 0.28 nf 0.48 nf
To:
44 0.70 nf 1.10 nf
Change #2
On page 14, Steps 14, 15 ,16 , 17 & 18 replace the Low Limit and the High Limit with:
Low Limit High Limit
99.93 kHz 99.97 kHz
199.48 kHz 199.52 kHz
99.93 kHz 99.97 kHz
99.93 kHz 99.97 kHz
999.8 Hz 1000.2 Hz
On page 15, Step 46, replace Low Limit and the High Limit with:
Low Limit High Limit
9.2 F 9.8 F

Change #3, 65782
On page 4, in the Symbols table, remove CAT III, CAT IV and CSA C1 and add:
Conforms to relevant North American Safety Standards
Conforms to relevant South Korean EMC Standards
CAT II
Measurement Category II is applicable to test and measuring circuits connected directly
to utilization points (socket outlets and similar points) of the low-voltage MAINS
installation.
CAT III Measurement Category III is applicable to test and measuring circuits connected to the
distribution part of the building’s low-voltage MAINS installation.
CAT IV Measurement Category IV is applicable to test and measuring circuits connected at the
source of the building’s low-voltage MAINS installation.
On page 5, replace Electromagnetic Compatibility and IP Rating with the following, and
remove Shock, Safety Compliance and Certifications and add:
IP Rating .................................................. IEC60529: IP67 (Non-operating)
Safety ....................................................... IEC 61010-1: 600 V CAT IV / 1000 V CAT III, Pollution Degree 2
Electromagnetic Environment ............... IEC 61326-1: Portable
Electromagnetic Compatibility .............. In an RF field of 3 V/M, accuracy = specified accuracy +20 counts, except
600 A dc range total accuracy = specified accuracy +60 counts.
Temperature not specified
Applies to use in Korea only. Class A Equipment (Industrial Broadcasting
& Communication Equipment) [1]
