ML0027 October 28, 2013 Copyright 2013 Bitronics, LLC
viii
If there is unlocked access to the equipment, care should be taken by all personnel to avoid
electric shock or energy hazards.
Voltage and current connections should be made using insulated crimp terminations to ensure that
terminal block insulation requirements are maintained for safety. To ensure that wires are correctly
terminated, the correct crimp terminal and tool for the wire size should be used.
Before energizing the equipment, it must be grounded (earthed) using the protective ground (earth)
terminal, or the appropriate termination of the supply plug in the case of plug connected
equipment. Omitting or disconnecting the equipment ground (earth) may cause a safety hazard.
The recommended minimum ground (earth) wire size is 2.5 mm2 (#12 AWG), unless otherwise
stated in the technical data section of the product documentation.
Before energizing the equipment, the following should be checked:
1. Voltage rating and polarity
2. CT circuit rating and integrity of connections
3. Protective fuse rating
4. Integrity of ground (earth) connection (where applicable)
5. Equipment operating conditions
The equipment should be operated within the specified electrical and environmental limits.
Current transformer circuits
Do not open the secondary circuit of a live CT since the high voltage produced may be lethal to
personnel and could damage insulation.
External resistors
Where external resistors are fitted to relays, these may present a risk of electric shock or burns, if
touched.
Battery replacement
Where internal batteries are fitted, they should be replaced with the recommended type and be
installed with the correct polarity, to avoid possible damage to the equipment.
Insulation and dielectric strength testing
Insulation testing may leave capacitors charged up to a hazardous voltage. At the end of each part
of the test, the voltage should be gradually reduced to zero, to discharge capacitors, before the test
leads are disconnected.

The M870D has three configurable parameters that must be set to match the device to which it is
connected. Press the up arrow key and the right arrow key simultaneously to enter the display
setup mode. The alphanumeric display will describe the selected parameter, while the digit display
will show the value. Use the up and down arrow keys to scroll through the available values for that
parameter. When the desired value is displayed, press the right arrow button to confirm the
setting. The left arrow button is used to go to the next configurable parameter. When ‘Exit’
appears in the alphanumeric display, press the right arrow key to return to normal operation. The
instrument will automatically return to normal operation if no keys have been pressed in
approximately 20 seconds. This timeout prevents the instrument from inadvertently being left in
setup mode.

PARAMETERS ARE STORED IN NON-VOLATILE MEMORY. THIS MEMORY
STORAGE HAS A 1,000,000 CYCLE ENDURANCE RATING. (PARAMETERS CAN BE
CHANGED 1,000,000 TIMES).
Note: Instruments produced prior to July, 2002 will display a ‘Remove Power!’ message when the
hardware setup has been changed. If this message is displayed, remove the input power to the
instrument for a few seconds and then reapply power. The instrument will go through its normal
boot sequence and the new settings will take effect.
3.3 Measurement Screens
Measurements that are shown on the M870D are setup using the Windowsbased 70 Series
Configurator. There are two folders in the Communication section, which must be configured
before the M870D can be used. The first folder is used to setup the Port Assignments, as shown
in Figure 3. Set the protocol of the port to which the Remote Display is connected to
Zmodem/Display/Log. Set the Media, Parity, and Baud settings as required. The RxD to TxD
parameter can be set to zero and the Run Display box must be checked. In this example, Port 1 is
set to run the display.
The Detached Display Folder must now be set up to show the proper measurements. Figure 4
shows the layout of this folder.
