Computorq-II Electronic Torque Wrenches
Catalog Link (PDF):  [Page 05]  



All New Electronics
Computorq II has the newest series of NEC microprocessors and surface mount technology available today.  This electronic torque wrench has the fastest sampling of torque measurements and update of displayed torque on the LCD of any wrench on the market.

Lower Profile
Height of LCD and keypad has been reduced 35% improving the wrench's appearance and allowing the wrench to be used in more restricted work areas.

Accuracy
±1% from 20-100% of scale ±1%, plus 5 increments, from 10-20% of scale.

Batteries
A 9V alkaline battery is standard and provides enough power for 60 hours of operation.  A "lo bat" indication on the display signals for replacement.  There is no loss of data in memory during battery change.  Batteries can be replaced in less than a minute.

Calibration Data
All calibration data is stored in the microprocessor.

Baud Rate
The baud rate for downloading to a computer is selectable.  The factory set rate is 1200.  Options are 300, 600, 2400, 4800, 9600 or 19,200.

 
Memory Storage
Up to 4000 torque values can be stored in memory.  An audible tone signals when memory is full.

Downloading
Computorq II is equipped to download individual torque values or store values in memory which can be directly downloaded to a computer via RS-232.
(Cable sold separately)

Modes of Operation
"Peak Hold" and "Track" modes of operations are standard and selectable. Computorq II's electronics are far superior to our competitors in capturing real torque value in "Track" mode.

Programming
Target torque values (high and low percentage, ±tolerances and torque engineering units) are easily programmed through the keypad and shown on the LCD.

Construction
Proven industrial quality and designed for continuous use.

New Liquid Crystal Display
Larger sized Super Twist liquid crystal display incorporates technology improving visibility of displayed data from any viewing angle.  The display is updated five times a second for changes in torque measurements.  There is no perceived lag between applying torque and updating the measurements on the LCD.  It is the fastest on the market.

Engineering Units
All seven basic engineering torque units are preset into Computorq II (Ft.Lb., In.Lb., In.Oz., Nm, dNm, Mkg, or cmkg) and are easily selected through the keypad.

Displayed Torque Measurements
Torque measurements captured on the display remain until erased, sent to the wrench's memory, or sent to an external device.

Recall of Torque Measurements
Up to 999 torque measurements can be reviewed by the operator, last in first displayed, by pressing the recall button.

 
Recall Display
When the recalled torque measurement is displayed on the LCD, the sequence number and total number of stored values are also displayed for reference.

Bar Graph
A bar graph is displayed on the LCD showing the relative position of applied torque to the preset torque range.  In "Track" mode, the bar graph displays the relative position of the applied torque to the full range capability of the wrench. The bar graph is updated 10 times per second.

Directional Indicators
There is a ± indicator on the LCD showing clockwise or counterclockwise application of torque.
Keypad
New embossing membrane keypad.  This new design gives a positive touch and response when any key is depressed.  Depression of any key is acknowledged by an audible signal giving a positive indication of acceptance.  The entire keypad is sealed against moisture and contaminants.

Sleep Mode
After a specified time period of inactivity, the wrench's display switches into a "Sleep Mode", conserving the 9V battery.  All memory is retained while in "Sleep Mode".  Operation may be continued by pressing the keypad.

 
On/Off Switch
There is an on/off switch to conserve battery life located on the side of the wrench.

Audio/Visual Indicators
Computorq II wrenches are equipped with both audio and visual signals in addition to the torque information supplied on the LCD.

Audio Signal
An audio signal is emitted when the minimum acceptable preset torque value is reached or the upper torque limit is exceeded.

Visual Indicators
Bright green and red LED’s are standard indicators of high and low preset torque limits.

 
Over-Load Protection
The red LED flashes and the audio buzzer sounds when the torque range of the wrench is exceeded. The display also indicates “OVER” in this condition.
