The TSV-1000 is designed for verification and calibration of non-contact tachometers and stroboscopes.
In tachometer mode the TSV-1000 sends out a steady, precisely timed stream of light pulses. Point a non-contact tachometer at it and compare the two displays. In stroboscope mode it works the other way round: it counts a strobe's flashes and shows the true flash rate, so you can confirm what the strobe says it is doing.
Ten programmable preset speeds let you step through the points you check most often, so routine checks are quick and repeatable. Cycle mode steps through all 10 presets automatically allowing operations to test a full range with ease. The TSV-1000 is made in the USA and ships with a NIST Traceable calibration certificate; an ISO 17025 accredited certificate is available as an add-on.

Manually or Automatically cycle through ten adjustable preset pulse rates. Hold the tachometer about 0.5 to 2 in (12 to 50 mm) from the pulsing LED. The tachometer should read the same as the TSV-1000, within the tachometer's own stated accuracy. Step through the presets to check it across its range. The display can be switched between RPM and Hz.
Works with non-contact tachometers such as the CDT-2000HD and the DT-205LR / DT-207LR in non-contact mode.
Switch to stroboscope mode and aim the strobe at the pulse sensor from about 3 to 24 in (75 to 600 mm) away. The TSV-1000 averages the flashes it sees and shows the actual flash rate in FPM or Hz, which you can compare with the strobe's own setting.
Suitable for hand-held stroboscopes such as the DS-2000LED and QB-LED. See all stroboscopes.
- In-house checks between outside calibrations for maintenance departments with many hand-held tachometers and strobes
- Quality records for ISO 9001 and similar audits, showing instruments were checked at set intervals
- Calibration and service labs that need a quick, repeatable pass/fail check before and after repair
- Incoming inspection of new or rental tachometers and strobes
- Printing, packaging and textile lines where strobe flash rate is used to set or inspect machine speed
- TSV-1000 calibrator with pulse sensor
- Universal AC adapter (100-240 V AC to 5 V DC)
- Calibration certificate
- Instruction manual
Calibration options: a NIST Traceable calibration certificate is included with every TSV-1000. An ISO 17025 accredited calibration certificate for the tachometer pulse output and stroboscope frequency is available as an option – select it in the Buy Now section below.
Can it check my laser or contact tachometer?
It is designed for non-contact tachometers, including optical and laser types, which read the light pulses from the sensor. Contact tachometers that need a rotating shaft or wheel cannot be checked with it. Combination tachometers such as the DT-207LR can be checked in their non-contact mode.
What test ratio does it give?
Supports 4:1 test accuracy ratio for instruments specified ±0.01% or wider, subject to digit/resolution allowance and verification at chosen test points. Each unit ships individually calibrated against a NIST-traceable reference; annual verification is recommended. The ±1 digit term is additional to the 25 ppm percentage term and must be included in the ratio: 4:1 is not guaranteed at every rate. Verify the applicable reference error/uncertainty allowance against one-quarter of the instrument tolerance, considering resolution, reference-counter certificate uncertainty, temperature and drift. No capability for instruments tighter than ±0.01%, full-range 4:1 guarantee or validated annual drift is claimed; the annual interval is a recommendation, not a validated stability period.
How do I check a stroboscope with it?
Put the TSV-1000 in stroboscope mode, set your strobe to a known rate and aim it at the pulse sensor from 3 to 24 in away. Compare the TSV-1000 reading with the strobe setting, and repeat at a few rates across the range you use.
What does the ISO 17025 option add?
An accredited ISO 17025 certificate for the TSV-1000 itself, for quality systems that require accredited calibration of reference equipment. A factory certificate is included either way.
