Display

Display device

Fluorescent display tube (selectable of three-stage brightness, 6-digit display)

Display refresh time

Selectable from 0.2 s (factory setting), 0.4 s, 0.5 s, 0.6 s, 0.8 s, 1.0 s to 10 s (in 1.0s step).

Unit of measurement

Number of decimal points

Selectable from OFF (factory setting), number of decimal point of 1, 2 and 3 digit

SIG indicator

Blink in synchronization with input signal

Error display

Backup memory error, board error, input frequency error, display digit error, memory full error, setup value error

Calculation

Calculation display

Rotation speed, circumferential speed, moving speed, period, times(1/s), frequency, flow, passing time

Measurement method

Periodic calculation method

Calculation time

10 ms + 1 period time

Measurement accuracy

Display value × (±0.01 %) within ±1 count

*The display value indicates the count value except the decimal point.

Auto zero function

The display value becomes zero with no signal input for the setup time in advance.

Selectable from below;
OFF (11 s), 0.5 s, 1.0 s, 2.0 s, 3.0 s, 4.0 s, 5.0 s, 6.0 s, 7.0 s, 8.0 s, 9.0 s, 10.0 s

Rapid deceleration follow-up function

If an input signal rapidly decreases and there is no signal input to tachometer approx. 1 second or more, measurement automatically decelerates with this function and then zeroed in approx. 11 seconds later.

Moving average function

Selectable from below:
OFF (factory setting), 2, 4, 8, 16, 32, 64, 128

*Analog output by TM-3130/0330 is obtained by the processing of
moving average with the calculation at every 10 ms.

Peak-hold function

Hold the peak value (maximum, minimum, average) between start and stop status.

Memory

Panel condition memory

Memorize 4 kinds of measurement conditions.
(The setup conditions can be stored and recalled.)
