The Snap-on VERSATORQ®2 is a portable, ATEX/UL certified electronic torque analyzer designed to display torque readings from sensors that attach between sockets and drivers. It functions as a versatile torque analyzer and data acquisition system, compatible with various accessories like sockets, extensions, universal joints, and ratcheting drivers.
Function Description:
The device features a wide-angle viewing LCD display that shows applied torque in either TRACK mode (real-time display) or PEAK-hold mode (displays the highest torque value captured). The display also indicates functions and fault conditions, including units of measure (ft-lb, in-lb, in-oz, Nm, cNm, kg, cmkg), an "OVER" torque alarm/message, a "LO BATT" battery monitor, and the active mode (TRACK or PEAK). A small 3-digit display shows the number of stored values.
The VERSATORQ®2 allows users to set high and low torque limits, which trigger an audible and visual alarm. Torque analyzer settings are entered via a push-button membrane keyboard. The device can store and recall up to 3500 readings and provides USB communication for PC interfacing and downloading. An audio output jack allows for the use of headphones in noisy environments. A belt clip on the back of the meter provides hands-free operation.
The torque analyzer and its optional sensors can be user-calibrated with a known torque input. Sensors incorporate a special memory chip that identifies their range and calibration parameters to any VERSATORQ®2 torque analyzer.

- Weight: 1 Pound.
- Charge Life: 100 Hours Continuous.
- Batteries: Three AA Alkaline batteries (Energizer E91, Panasonic LR6XWA, Duracell MN1500 are specified).
- ATEX / UL Certified: DEMKO 16 ATEX 1699X.
- Hazardous Location Designation: Class 1, Zone 2, Ex ic IIA T6.
- File Number: E484919.
- Data Storage/Recall: 3,500 Measurements.
- Sensor Overload: Sensors can withstand an overload of 120% of full range.
- Sensor Excitation: 3.3 volts DC. Gages are sampled 3 times/second and always sampled at 320 times/seconds when input exceeds 1% of sensor range.
Usage Features:
- Power ON/OFF: The power switch on the side of the unit controls power and sleep mode. The unit performs a self-check at power-on and automatically identifies the installed sensor, setting rated units for display.
- ZERO TARE: Automatically sets to zero at power-on or when changing sensors. Manual ZERO TARE is also available via a button. It is crucial not to apply torque during start-up or when pressing ZERO TARE.
- UNITS Selection: The UNITS button allows selection of desired measurement units (ft-lb, in-lb, in-oz, Nm, cNm, cmkg, kg).
- SET-UP Mode: Used to set preset torque values, MAX torque percentage over preset, MIN torque percentage under preset, and to select TRACK or PEAK mode. Navigation and value adjustment are done using arrow keys.
- TRACK Mode: Displays real-time torque values as they are applied. An audible continuous tone and green LED indicate when MIN preset torque is reached. A pulsating tone and red LED indicate when MAX preset torque is reached.
- PEAK-HOLD Mode: Captures and holds the highest torque value applied. The reading increases if additional torque is applied and automatically clears when torque is reapplied. Alarms function similarly to TRACK mode.
- Memory Functions:
- STORE: Saves the current torque reading (in TRACK mode, while torque is applied; in PEAK-hold mode, after capture).
- RECALL: Displays previously stored readings in descending order.
- CLEAR: Clears the last reading from the display. To clear the entire memory, press RECALL then hold CLEAR for approximately three seconds, or delete the CSV file on a PC.
- Data Downloading: Connects via a MINI-USB port to a PC to off-load stored data as a .csv file, which can be opened in spreadsheet software like Excel.
- Sleep Mode: Automatically shuts off after five minutes of inactivity to conserve battery life.
- Sensor Connection: Uses a DE9P subminiature 9-pin male connector. Sensors feature full bridge, 350 ohm, strain gages.
- Alarm Sounder: Produces a 2 KHz continuous tone at MIN preset torque and a pulsating tone at or above MAX torque. Also sounds momentarily at each keypad entry.
Maintenance Features:
- Cleaning: Clean the meter by wiping with a cloth. Do NOT use solvents, thinners, or carburetor cleaners. Do NOT immerse the device in any liquid.
- Service and Repair: Service, repair, and calibration must be performed by Snap-on Service Centers only. Users should contact their Snap-on Tools representative for assistance.
- Calibration: The device is factory calibrated to NIST traceable standards (ISO 6789-2003 and ASME B107-28-2010). Calibration events are recorded in memory. Users can also perform sensor calibration with known torque inputs, following specific procedures for clockwise (CW) and counter-clockwise (CCW) directions, requiring a precision calibrated test bar and certified calibration weights, and new specified AA batteries.
- Battery Replacement: Use only specified AA batteries. DO NOT replace batteries when an explosive atmosphere is present.
