The 2000 Series
Railroad Test Sets
The 2000 Series Railroad Test Sets from
Triplett Corporation are specialized VOM's designed for measuring the
signal parameters of railroad coding equipment. They maintain
compatibility with older technologies, while offering functions and
features not found on standard VOM's.
Even for normal operation, the 2000 Series
Railroad Test Sets are easier to use. Fewer jacks, more ranges, and a
logical front panel layout all contribute to the 2000 Series' ease of use.
The use of a multi-turn Ohms Adjust Control facilitates accurate
resistance measurements. Also, the measurement of relay contact on time
has been simplified and expanded requiring no adjustments.
Code Parameter measurements have been made
simpler and more accurate. No longer is it necessary to count pointer
swings to measure code rate. On Time can be measured on live signals as
well as relay contacts. Peak Levels can be determined quickly and
automatically. Adjustments to the code equipment peak level can also be
made without constantly readjusting the Test Set. The 2000 Series Railroad
Test Sets are also expandable. Optional circuit boards may be installed at
any time to allow for the filtering of 60Hz, 100Hz, 200Hz, or 250Hz Cab
Signals. The base unit Model 2000 may be upgraded at any time to include
these filters without losing your initial investment.
The 2000 Series Railroad Test Sets from
Triplett Corporation, once again, leaving the competition dead in its
tracks!

2000 SERIES ENHANCED FEATURES
Auto-polarity on all DC
functions with red NEG indicator. Ohmmeter Voltage Mode detects
foreign voltage of either polarity. Multi-turn Ohmmeter Adjust
for more accurate setting of Ohmmeter zero. Power saving sleep
feature prevents draining of the batteries if accidentally left
on. Dry contact requires no adjustment to measure relay contact
on time. Measures rate directly without counting pointer swings.
Can detect and hold 2 msec momentary closures. Selectable DC
Amps Polarity (Auto, Positive, Negative). Will measure pulse
code transmit and receive currents independently.
-
DIRECT MEASUREMENT OF CODE PARAMETERS
Directly measures code
parameters in any AC or DC range. No counting of pointer
swings or adjustments are necessary. Peak Follow allows
downward adjustment of peak levels.

On Time
Accurately measures code
parameters to 420 cpm.
CAB FILTER OPTIONS (2001,2002, & 2003)
Allow measurements of all
code parameters for selected cab frequencies without shutting
down equipment. Active in all AC Volts and AC Amps Ranges.
SAFETY FEATURES
Shrouded safety jacks and
spring-loaded shroud on test lead plugs. Fused on all ranges and
functions except 6A and 30A. Battery/Lamp Test and Battery
Monitor prevent false readings from weak batteries.
MECHANICAL FEATURES
Rugged, lightweight,
weather-resistant case. Secondary protective window (field
replaceable). Modular construction for easier repair and
upgrade. One Year Warranty on construction and calibration.
