Includes two PC Windows based software programs:

PTT Interface Program- for sensor calibrations, meter calibration and tool tests,

PTT Bootloader - for updating the PTT operating systems.

Mountz Statics Calculator - for SPC, CP & CPK calculations.

“Flash" memory allows upgrades to be done by the user in the field & internet through the USB port.

Five low-pass filter selections (3000, 2000, 1500, 500 and 200 Hz).

Easy to use Menu Structure.

Real Time Clock for time stamping of readings.

Six-digit display.

USB interface to download readings to PC.

High Capacity Li-Ion Batteries for long life (30 hrs with standard transducers and 16 hrs with brushless rotary).

Can connect to most mv/v transducers and can store calibration data for up to 50 non smart torque sensors.

The 5VDC capability allows unit to be used with a Brushless Rotary Transducer for testing pulse tools and high

RPM tools.

Torque and Angle readings are displayed simultaneously and supports up to 8000 RPM.

Stores a total of 2500 data points.

Real time graph of torque vs. time using associated PC Windows software.

Screen Display

When the Torque Analyzer is turned on and it is connected to a Mountz "Smart" Torque Transducer with ARCII

technology it will display a Screen similar to that below for 5 seconds and then go into Reading Mode. This will also

happen if a "Smart" transducer is disconnected and another smart transducer is connected.

If an un-calibrated transducer is connected then the Analyzer will display a screen as below.

Note:

The PTT supports Non-Smart transducers and Non-Mountz transducers. Non-smart transducers can be

detected and can be calibrated in the "internal" memory. The PTT will offer 2 choices. It offers to calibrate or

choose from a list of transducers stored in the internal memory.

Mode Selections

This mode constantly tracks increasing or decreasing torque

variations. Use this mode to monitor varying torque on motors

and machinery. Also for calibration and testing of dial torque

products (small wrenches or dial screwdrivers).

The display retains the highest torque applied. Use this mode

during calibration or testing of any hand type torque wrench

(dial, beam, and screwdriver), as well as power tools.

Peak

Menu Tool Tests

The display holds the first detected torque peak applied. Before any

torque is applied, the display show dashes in the torque value area.

Once peak is detected, the display will show the torque value. If a

second peak is detected then it will be displayed in the lower right (in

small reverse video).

This function is primarily used for testing and calibrating click type

mechanical torque wrenches. The PTT captures the point where the

wrench clicks. This peak may be used for operator training on correct

use of the wrench. Always apply torque smoothly to avoid false first

peak readings.

This mode is used to determine “first movement” or what is commonly

known as “break-away” torque to determine the actual torque on the

joint. An angle enabled transducer is required to operate in this mode.

This allows an operator to set up an initial torque and follow up with a

rotation to a specified angle and display the final torque.

The PTT can collect Torque and Angle data if the unit is connected to a

transducer that includes the angle function. It is a "Real Time" angle

function that can capture Torque and Angle up to 8000 RPM.
