•LCD display ¼ VGA (320 x 240 Pixels) with graphical user interface
•Wide measuring range with auto ranging
•Display of vector diagram for analysis of mains conditions and meter connections
•Measurements of wave forms and harmonics with display
•Easy detection of circuit connection faults
•Data memory for test results and customer data
•Small dimensions and light in weight
•Serial interface (RS 232) for data transfer
Functions
•Active, reactive and apparent energy measurement with integrated error calculator
•Impulse output for energy (galvanic isolated)
•Registration of active, reactive and apparent energy for register testing
•Active, reactive and apparent power measurements
•Current and voltage measurements
•Phase angle measurement
•Power factor measurement
•Frequency measurement
Options
•Software CALSOFT for memory readout, online data logging, presentation and printout of results
and customer data.
•1 clamp-on CT1000A (Measuring range: 100 mA … 120 A, cable : max. 52 mm

Neutral Connection for voltage N
Connection: 4 mm black insulated socket
LINE / Inputs 46V … 300V
CAT III 300V 47Hz … 63Hz
Attention! The voltage between voltage termi-
nals ([1], [2]) and to protecting earth shall not ex-
ceed 300 V, if the instrument is applied in meas-
urement category CAT III environment.

Connection for clamp-on current transformers
•1 active 100A error compensated clamp-on CT (Standard accessory)
•1clamp-on CT1000A (Measuring range: 100 mA … 120 A, cable : max. 52 mm)
(OPTION)
Connector type: 9 pole dedicated Redel socket, suitable for special MTE clamp-on cur-
rent transformers.

Impulse input / output
This input can be used for scanning heads (such as the SH 2003) and can also be used
to connect to retransmitting contacts of the device being tested.
The connector can also be configured as output (Pin 3: fout, Pin 4: GND) in the installa-
tion menu to calibrate the instrument with a higher class reference standard.
Connector type: 5 pole Lemo socket,
Pin 1 +11 to 13V (I<60mA) (DC supply to scanning head)
Pin 2 fin max. 100 Hz (slow input, anti-bounce)
Pin 3 fin max. 200 kHz (fast input) or fout max. 10 kHz
Pin 4 GND

4. Start-up of the instrument
Before start-up of the instrument carefully read the safety precautions in chapter
1.
Examples of connections using the CheckMeter 2.1 for measurements on different types of devices
under test and for various connection modes are given in chapter 9.
Attention! Disconnect or switch off dangerous voltages in the measuring set-up during
connecting or disconnecting the CheckMeter 2.1 whenever possible. Regard local
safety regulations for connection of measuring instruments to the installation.
Steps to connect and disconnect the CheckMeter 2.1
Connect
1.
Connect clamp-on CT at the CheckMeter 2.1
2.
Connect scanning head SH 2003 or hand switch at the CheckMeter 2.1, if used.
3.
Connect the supply of the CheckMeter 2.1:
Supply from auxiliary voltage
Use the standard two pole supply cable. The instrument will immediately power-up.
Supply from measuring voltage
The instrument is automatically supplied from measuring voltage U1-N, if no auxiliary voltage
is connected.
The instrument will power-up as soon as the measuring voltage is present.
Attention! The supply voltage of auxiliary source or measuring voltage must al-
ways be in the range: 46 to 300 V, 47 to 63 Hz. Higher voltages may damage the
instrument.
4.
Connect voltage cables first at CheckMeter 2.1 and then at measuring set-up.
5.
Fix clamp-on CT on wire of measuring set-up.
Disconnect
1.
Remove clamp-on CT from wire of measuring set-up.
2.
Disconnect voltage cables first at measuring set-up and then at CheckMeter 2.1
3.
Disconnect supply to CheckMeter 2.1:
a) Disconnect from auxiliary voltage supply
b) Remove connections for supply from measuring voltage
4.
Disconnect scanning head SH 2003 or hand switch at CheckMeter 2.1, if used.
5.
Disconnect clamp-on CT at CheckMeter 2.1.
