Dillon GTS-1000 - Manual (Page 11)

#1 Operating MODE
The GTS-1000 has two operating modes, marked by an LED on the console. Press to
cycle between:
1. Manual. Once UP or DOWN is depressed, the crosshead moves until any of the
following occurs:
a. Either MOVE key is pressed
b. A limit switch is tripped (in the appropriate direction)
c. The emergency stop button is pressed
2. Auto-reverse. This mode can speed up your repetitive batch testing. It runs at
test speed until it reaches the travel limit and then automatically reverses,
traveling at wide open throttle back to the other limit switch. You can stop the
stand at any time by pressing the UP or DOWN key or Emergency Stop button.
CAUTION
Auto-reverse mode is not suitable for tensile testing
when the sample must be removed before lowering,
such as ductile metal parts.
The Dillon GTX force gauge offers increased stand control.
- In Manual mode, the GTX can stop the stand upon sample break detection.
- In Auto-reverse, it can reverse the stand upon sample break detection.
The GTX also interrupts downward travel when gauge capacity is exceeded to reduce
potential for overload.
See accessories for the GTX stand reverse cable.
CAUTION
The overload detection within the GTX is intended as
a backup approach to help reduce accidental
overloads under slow speeds. The GTX must NOT be
the primary method to prevent overload.
#2 Test SPEED
The GTS-1000 features speed selection keys and a speed display. The and keys
adjust the crosshead speed shown on the LED display. The speed adjustment is slow
initially, but then increases the rate when held down.
Speed may be adjusted while stopped or while moving. Full speed return in auto-
reverse mode is not adjustable.
WARNING
Take care when adjusting speed up while crosshead
is moving. Speed may rapidly increase.
