MINILEVEL NT

COMBINED WITH THE

LEVELMETER C25 (

ANALOGUE DATA TRANSMISSION

)

Analogue data transmission

One or two MINILEVEL NT connected with a
LEVELMETER C25

This configuration does not allow the use of wireless transmission because the LEVELMETER C25 is an
analogue display instrument

IMPORTANT:

The measuring instruments must be switched ON via <ON/OFF> button the

red LED must be blinking rapidly. With another short push to the button the sender/receiver may be
stopped. Local measurement with the instrument only. The red LED is blinking slowly.

LEVELMETER C25

IMPORTANT:

The display on the MINILEVEL NT is in µm/m or Arcsec.
The display on the LEVELMETER C25 is in digits only (sensitivity unit) in order to receive the
correct measured value the value must be multiplied by the sensitivity set on the MINILEVEL
(Range I or II)

Switch (Backside)
"On" / "Off"

Switch for LEVELMETER. The low battery
indication (XX:XX colon) is appearing
automatically during operation if battery power is
insufficient.

LEVELMETER C25 / DC

Potentiometer:
"ZERO" (1)

Enables adjustment of the zero point. The
regulating range is min. +/- 400 digits.

Socket A (2)

Input for measuring with

one

MINILEVEL „classic“

Socket -B (3)

Input for the reference level in differential mode.
In order to prevent interference voltage to
channel A , input B is switched off when no
instrument is connected.

Socket:
"POWER/OUT (4)

Analogue output 1 mV per digit.
External power supply input.
