Summary of Contents for Meatest M160
- Page 6 Precision DC calibrator M160 is an accurate source of DC voltage and DC current. It offers thermocouple and RTD simulation and some other features suitable for process calibrations. Calibrator is designed for use in production, but can be used also for development or in calibration laboratories.
- Page 7 All input and output terminals are located on left side of front panel. 1. Voltage/Current terminals - HI / LO are two wire output terminals. LO terminal is floating up to 50Vpk against the case (PE). 2. Voltage sense terminals - S / S are sense terminals for four wire voltage configuration. 3.
- Page 8 Display is divided into several sections with following meaning: 1. Selected function. Symbol on the left indicates system status ( standby, settling in, ► running). 2. Softkey labels. Softkeys below the display change their function dynamically based on current workspace, these labels describe Softkey functions at any given time.

- Page 10 When controlled remotely, maximum ratings of calibrator’s output signals as well as all other specifications are the same as in manual mode. Meatest software package WinQbase + Caliber is recommended for best automation results. This system is designed for automated and semi automated calibrations of digital and analogue meters including...
- Page 11 LAN communication uses Telnet/TCP/UDP protocol. Default log-in for client is “M160_SNxxxxxx 23”, where “xxxxxx” stands for serial number and 23 is default communication port (22 for TCP and UDP protocol). See M160 SCPI manual for complete SCPI reference, more details on communication setup and troubleshooting.
- Page 12 Inspect package contents when unboxing the calibrator for the first time. See chapter 1.3 for complete list of accessories. Place the instrument on a level surface before powering on and let it stabilize for at least one hour if the instrument has been stored outside of reference temperatures beforehand.
- Page 13 The calibrator must be powered by 230/115 V – 50/60 Hz mains. Before connecting the instrument to the mains, check the position of the mains voltage selector located on the rear panel. Set appropriate voltage selector position either 115 V or 230 V. Plug one end of the power cord into connector on the rear panel and connect the other end of the power cord into a wall outlet.
- Page 14 Function can be changed after pressing „Function“ softkey. New function is selected using cursor keys ▲,▼ or display softkeys. Selection must be confirmed by pressing SELECT key, ENTER key or „OK“ softkey. Calibrator output can be turned on by pushing OPER button. Pressing OPER button again turns output off.
- Page 15 If an obvious failure occurs during the operation (e.g. the display is not lit, the fan is not turning), the calibrator must be switched off immediately. First, check the fuse located in the power cord receptacle. Procedure is following: - Remove the end of power cord from the mains connector at the rear panel. - Insert the blade of a flat screwdriver into the opening cut in the mains voltage selector and pry out the fuse holder.
- Page 16 Main menu is displayed after pressing „Menu“ softkey. Main Menu allows configuration and calibration of the device Four buttons on the front panel give access to main menu sections: Main menu is the most comprehensive setup tool of the calibrator, containing information like serial number, calibration date or display brightness as well as remote control interface setup or calibration constants.
- Page 17 Interface menu contains remote control connection settings: Calibration menu contains internal calibration constants and other tools for device adjustment and is therefore password protected. See chapter 6 for more details on M160 adjustment. Calibration menu has following items: 1. Data. Contains current calibration data. Structure of this menu is described in chapter 6.1.
- Page 18 Backup function allows you to save and recall entire sets of calibration data. Calibration data are also saved automatically when any calibration value gets changed, creating a record with “Auto” storage (or overwriting an existing one if the last change occurred within last 90 days). Use softkeys to save and recall previously stored calibration data sets: 1.
