DESCRIPTION
1. PURPOSE OF MANUAL
A. This publication contains the description, operating procedures for the:
TT-1000A DIGITAL TURBINE TEMPERATURE TEST SET, P/N 101-00901
(Refer to Figure 1.)
Manufactured by:
Barfield Inc.
B. This manual is released to address the TT-1000A which is designed to test and
calibrate Chromel-Alumel (CH-AL) temperature indicating systems.
2. GENERAL DESCRIPTION
The TT-1000A provides the means for quickly troubleshooting aircraft temperature
indicating systems. It has sufficient sensitivity and accuracy to test thermocouple and
system resistance, insulation, and indicator calibration. It features portability, simplicity
of operation, direct reading, and multi-functional versatility.
A. TT-1000A Features;
(1) Specifically designed to meet all requirements for testing aircraft
Chromel-Alumel (CH-AL) temperature measuring systems and provides an
accurate display of thermocouple outputs in degrees Celsius (oC).
(2) Thermocouple and lead resistance measurements to 0.01 Ωand insulation
measurements up to 2 MΩ.
(3) Simulates thermocouple outputs and system lead resistances from 0 to 25 Ω.
(4) Completely self-contained, self-monitoring, easily portable temperature and
resistance measuring and simulating device for all CH-AL systems with the
capability to bench test indicators.
(5) Human engineered for maximum ease of operation and maintenance with
state of the art low battery drain circuitry with automatic ambient test point
temperature correction.
(6) A large, 0.35 in. (9mm) high characters, 3 1/2 digit Liquid Crystal Display (LCD)
with preprogrammed legends.
56-101-00901-D Page 2 of 19
(7) Carrying Case features;
(a)Fabricated from drawn aluminum for maximum strength.
(b)The lid has been fitted with a bracket which, when the lid is closed,
contacts the "ON/OFF" switch, in the "ON" position and moves it to the
"OFF" position.
(c)Provides, on the right hand side, space for test lead storage.
(d)The lid also contains a placard presenting abridged operating instructions
for the experienced technician.
NOTE
:For personnel without experience, it is advisable to become familiar
with this publication, the TT-1000A, and the equipment with
which it is to be used BEFORE performing any test or checks.
3. SWITCHING FUNCTIONS (Refer to Figure. 1)
A. The "ON/OFF" switch (1) applies power for all functions.
B. The "TEMP. ADJ." control knob (3), a ten turn potentiometer permits exact
adjustment of the millivoltage generator for temperatures which are displayed on
the LCD (2) as oC when the "FUNCTION" switch (4) is in the "INDICATOR TEST"
position.
C. The "FUNCTION" switch, a three position rotary switch that permits selection of the
three principal test functions, "RESISTANCE MEASURE", "INDICATOR TEST"
and "TEMP. MEASURE".
D. The "PUSH TO MEASURE ACFT. LEAD RES." BLACK pushbutton (5), when
depressed with test leads connected to aircraft system and "FUNCTION" switch in
"RESISTANCE MEASURE" position produces a display of the resistance in the
system.
E. The "SHORT TEST LEADS AND PUSH TO SET SYSTEM RES." RED pushbutton
(6), when depressed with test leads shorted and the "FUNCTION" switch in the
"RESISTANCE MEASURE" position connects the "SYSTEM RES." potentiometer
for system resistance adjustment.
F. The "RESISTANCE RANGE" switch (7), a four position rotary switch, permits
selection of the resistance range, 20 Ω, 200 Ωor 2 MΩ- (0 Ωsystem resistance)
and "BAT" position for monitoring the 45-volt battery.
