HT-6200 is a handheld tachometer with a built-in batteries designed for measurement of gasoline/diesel engines, EV/HEV motors, and general rotating objects. Combined with optional detectors (VP-202/1220, IP-292/296, IP-3000A, IP-3100, OM-1200/1500, MP series and TTL signal output detector etc.), various rotation measurement are possible depending on the measurement objects or purpose.

 

 

Measurement may not be possible or the measurement range may change according to the type of an engine. Please consult your nearest distributor for more details.

 

Features

  • Rotation measurement of EV, HEV motors, and gasoline&diesel engines
Applicable detector: Choose the detector depending on your application.
Engine IP-292/296 Ignition pulse detector
IP-3000A/3100 Ignition pulse detector
OM-1200/1500 Motor Gasoline engine RPM detector
VP-202/1220 Engine vibration detector
Motor OM-1200 Motor/gasoline engine RPM detector
General rotating object MP series electromagnetic rotation detector

  • Up to 20 data can be stored. (Built-in memory function)
  • The maximum and minimum values can be displayed during measurement. (Peak-hold function)
  • Analog, monitor and pulse outputs are provided.

 

Analog output Outputs to the display value of rotation speed. (for recording of rotation speed)
Monitor output Outputs sensor signal after wave-form shaping (for checking waveform of detected signal )
Pulse output Outputs one pulse for each signal detection (for rotation synchronous signal)

 

  • Large LED with backlight useful for checking the displayed value in dark place

  Gasoline, diesel engine rotation measurement Rotation measurement other than an engine
Measurement unit r/min (rotation speed) r/min, r/s (rotation speed), m/min (line speed),
ms ( cycle ), COUNT (accumulated count)
Input frequency range 1 to 1666.67 Hz 3.33 to 1666.6 Hz
Maximum measurement value 20,000 r/min
(The maximum rotation speed is 20000 r/min regardless of the number of pulses per rotation.
99999 r/min (P/R), 999.99 r/s (P/R=1), 9999.9 m/min (diameter= 100 mm), 300 (ms), 99999 (COUNT)
The maximum value changes with the number of pulses per rotation.

Object to be measured Engines, motors and general rotating objects
Display 5-digit LCD with backlight (character height: 10.2mm)
Calculation method Periodic operation method
Measurement time 1s + one-period time
Measurement accuracy Displayed value* x (±0.02 %) ±1 count
* The displayed value is the count value excluding figures after the decimal point.
The measurement accuracy of the line speed depends on the accuracy of rotation speed (r/min) .
Setup range of the number of pulses (P/R) 0.50 to 200.00 (engine rotation measurement)
0.50 to 999.99 (other than engine rotation measurement)
(can be set in 0.01)
Measurement function  
  Peak hold function Maximum value (MAX), minimum value (MIN)
Memory function 20 data (MAX)
Over-range function The over-range (ERROR mark) is displayed when the measured value exceeds the display range.
Upper limit rotation warning function The upper limit warning (↑ mark) is displayed when the number of rotations exceeds the preset upper limit value.
Line speed calculation function Calculates the line speed from the preset diameter value (mm) and the measured number of rotations
Accumulating function Cont accumulated pulses of input signal
Cycle measurement function Measures the input pulse cycle
(however, when the cycle is less than 1 s, measures the mean value of the input pulses)
Trigger level adjustment function Trigger level can be adjusted using a rotary dial at the right-hand side of the device.
