|
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. |
