This item is a Simpson Model 269 analog volt-ohm-ampere meter. It can
measure DC voltages to 4000 volts, AC voltages to 800 volts, and DC
current to 8 amps. The AN/ USM-486 can measure DC voltages to 6000
volts with high voltage probe, AC voltages to 750 volts, and DC current to
2 amps. Use the AN/USM-486 where the additional AC voltage and DC
current to 2 amps. Use the AN/USM-486 where the additional AC voltage
and DC current capabilities are not required. Otherwise, retain the
AN/USM-123.
This item is replaced by the TEMOD item when used as a function

E101
The SG-1171/U will replace this item in all applications except where it is
used to perform AH-1 SCAS testing. These units will retain this item until
the SG-1288/U is fielded.
E102
The AN/GSM -64D can potentially replace the ME-498. The AN/GSM -64D
does not measure above 1000 volts AC and the ME-498 measures up to
1200 volts AC. Units not requiring measurements over 1000 volts DC
should use the AN/GSM -64D.
E103
The SG-1170/U will replace this item for all applications except where it is
used to support testing of the AN/ARN -83. These units will retain this
item.
E104
The AN/GRM -114B is an enhancement of the AN/GRM -114A. The
AN/GRM -114B is the Army's next generation radio test set used for field
support of single channel and SINCGARS frequency hopping radios. It
will be used to verify radio performance characteristics and troubleshoot
at the Direct Support (DS) level of maintenance.
The AN/GRM -114B consists of two components. The General Purpose
test functions to verify the performance characteristics of single channel
radios and the Special Purpose test functions to verify the performance
characteristics unique to the SINCGARS radios. In terms of improved
operational effectiveness, the AN/GRM-114B will execute SINCGARS
radio performance tests in three minutes instead of the current 25
minutes.
Advantages of the AN/GRM-114B over the AN/GRM -114A are that it is
more reliable, easier to use with computer like menus, and allows the
execution of radio performance tests with the touch of a button. It also
requires less time to repair.
The AN/GRM -114A's will not be removed from the field, but replaced by
the AN/GRM-114B through attrition.
This item is a Simpson analog volt-ohm-ampere meter. It can measure
E105
DC voltages to 5000 volts, AC voltages to 5000 volts, DC current to 10
Amps and decibels -20 to +4.9 dbm. The AN/USM -486 can measure DC
voltages to 6000 volts, AC voltages to 750 volts, and DC current to 2
Amps. Use the AN/USM -486 where the additional AC voltage, DC current
and decibels measurements capabilities of the ME-450 are not required.
Otherwise, retain the ME-450.
This item should be removed from the field and replaced by the ME-563/U
E106
when this item is used to measure amps only.
