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.

4 Graphics display
The LCD Display is divided into two parts. The upper part is for the multimeter functions, the lower part for the
calibrator. The bargraph in the middle is the analogical representation of the measured input signals. The left side
shows various symbols:
Symbols in the upper display part
AUTO Automatic Voltage Range or firm measuring range
200V Measure Ranges 2V, 20V, 200V, 100mA
INP The display shows the input signal.
Symbols in the lower display part
RMP Automatic Ramp of the calibrator signal
SUP The battery is being charged
60% Battery voltage in %. Do not run the instrument when the battery shows 0%. Charge only with the
enclosed original charger.
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.

For fast diagnostics of external signals measured by the multimeter the graphics representation can be displayed.
Two modes of operation are available:
- GRAPHICS the running measurement is automatically stored in 128 points (FI-FO)
- TRANSIENTS Eight individual memory slots are assigned for fast signals –Transients.
The sampling time and the Trigger level are selectable.
The Memory module for the Graphics and the Transients are common. By recalling the Transients, the Graphics
will be erased.
7.1 GRAPHICS
The key GRAPH opens the graphic presentation.
Graphics deactivated - GRAPH OFF. The graphics can be activated with vertical cursors - GRAPH ON.
The latest stored signal will be displayed when OK is pressed.
