Datalogger Function in M505 D model
M505 is a Calibrator-Multimeter for generation of Currents 0-22mA Sink or
Source und Voltages to 25VDC. External voltages ±2V, ±20V and ±200VDC
(firm ranges or auto ranging) and Currents to ±100mA can be measured
simultaneously and shown at the display.
Further Functions contain generation of calibration mV Signals, Thermo voltages of DIN Thermocouples and RTD
Resistors and simulation of true resistors.
mV voltages of 0-27mV or 0-540mV are mainly used for calibration of Strain Gauges, Transmitters and small
signal inputs with resolution of up to 0.001mV.
Thermocouples J, K, N, R, S, T, B, E are simulated. The temperature is entered with the keyboard and shown at the
display. The cold junction is compensated to the ambient temperature. It can also be switched-off.
RTD Thermometers can be simulated within the DIN temperature range. The temperature is entered with the
keyboard and shown at the display.
Ohm Source Resistance values up to 3kOhm are simulated. The resistance value is entered with the keyboard and
shown at the display.
Graphics and Memorising of measured signals is a standard function. The signals are continuously stored and
shown at the display as graphics. In apart of this eight memory slots for storing of fast signals -Transients- are
available. They can individually be stored and selectively recalled at the display.
Datalogger is an Option. The calibrating signals and the multimeter input are shown at the display and stored as
tables with date and time from internal RTC. They can be downloaded to the PC and edited under Windows and
Excel. A software program is available for Windows.

CONTROLLER
The Functions of the Calibrator and the Multimeter are selected with the keyboard and supported by a
microcontroller. The factory settings and the calibrated points are stored in a nopn-volatile memory and remain
stored also when the instrument is switched off. The software calibration of all ranges is accessible in the
calibration menu and protected with a password. All ranges can be recalibrated via the keyboard if required.
The graphic display is divided into two windows. The upper window is shows the multimeter functions, the lower
window the calibrator. In programming mode the display shows the parameters. In graphics mode of operation the
display shows the stored input signals.
The Multimeter is always active and can be used independently from the calibrator. The ranges can be selected
with the keyboard. The current range is firm. The voltage ranges are firm 2V, 20V or 200VDC or can be set as
automatic range.
Minus Terminals of the Calibrator and the Multimeter are common.

5 Datalogger (Software Option)
The generated signal and the measured signal are stored in a table format. The date and the time are added. The
stored data can be downloaded via the USB to a PC. A Soft Manager supports the data transfer to a Windows PC.
Two Set Points LEVEL LOW and LEVEL HIGH and two Intervals INTERVAL 1 and INTERVAL 2 will be
selected. If the measured signal is between the both Set Points LEVEL LOW and LEVEL HIGH, the data will be
stored with INTERVAL 1. The INTERVAL 2 stores the date when the input signal is outside the Set Points. The
both Intervals can be selected from 2 sec. to 24 hours.
With the key LOGG is the function Datalogger active. The key MENU and the two cursor keys permit the
parameter selection. With OK the setting will be stored.

11 Datalogger (model M505D only)
When the function Datalogger is activated, the calibrator output and the multimeter input signals will be stored in
the internal memory. This permits fast checking of transmitters and their calibration in the field.
Example: A T/C transmitter with mV input signal generates 0-10V at the output. Both signals are stored as a table
with date and time added from internal RTC.
The Data can be downloaded to the PC and displayed as tables and graphics. They can be used for Excel and
handled under Windows.
Set Points LEVEL LOW and LEVEL HIGH and Intervals INTERVAL 1 and INTERVAL 2 will be selected. If
the measured signal is within the set points LEVEL LOW and LEVEL HIGH, the data will be stored with
INTERVAL 1. Outside the set points the Data are stored with INTERVAL 2. The Intervals are programmable
from 2 seconds to 24 hours.
