Specifications

Measuring Function Principle

Pulse distance measurement with automatically extended number of periods,
as determined by a programmable* minimum measuring time allowance.
Low end of operating range programmable*, high end = 100 kHz.
Accuracy + 0.05 % + 1 in last active digit.
Special Function (SF) provides continuous totalizing of input pulses.

Modes of Operation

Push-button selection between FIX = straight tachometer function and
VAR = use of incorporated programmable* computing facilities.

Computing Facility to convert Measurements into other Variables

6 digits programmable* conversion factor, multiplying or dividing, representing
a roll circumference, or gear ratio, or transmitter factor, for instance.

Display

6 digits reading speed by selectable units .../sec, …/min, …/h, or totals (SF).
Decimals by automatic shifting (FIX mode) or firm on programmable position
(VAR mode).

Memory

Maximum, Minimum, Average, over a controllable period of time. Call to
display by push-button.

Signal Input

To pulses or AC voltage from 50 mV

eff

up to 60 volts. Selection of automatic
response characteristics. Programmable* frequency pre-divider 001 …255.
Sensor supply 5 volts / max 60 ma.

Analog Output

0 … 4 volts, short circuit protected. Source impedance 100 ohms. Linearly
related to display. Low and high end of conversion range programmable* for
spread reading. Resolution 12 bit.

Pulse Output

Square wave shaped, with its sequence repeating the input, reduced by pro­grammed pre-divider. 5 volts TTL-level.

Power Supply

Inserted batteries (4xMN1500), or rechargeable cells (IECR6). Alternatively by
supply unit (U1H008) from mains 100 ... 250 volts AC, plug-in connection.

Operating Conditions

Ambient Temperature -10 … + 55 °C (14 … 130 °F). Protection grade IP 54.
Dimensions 195 x 100 x 40 mm. Weight (with batteries) approx. 480 grams.

* Programming effective only in VAR mode. Parameter List on page 14.

For additional specifications of special versions see corresponding chapters.
