Long press the setting will flash.
Use and to choose Options.
Long press for confirmation.
Password Entry
Setting-up mode is password protected, so you must enter
the correct password.
By firmly pressing the button for 3 seconds, the
password screen appears.
The default password is 1000.
If an incorrect password is entered, the display shows ERR.
Programming the meter
When you receive the meter there will be at least one value that you must
programme into the meter. This is the current transformer ratio.
If the meter has been purchased with the intention of using the RS 485
Modbus output then you will have to program the Modbus parameters you
require. See reverse Communication. (RS 485 Modbus)
HT-1095 METER
From the main Set-up menu, Use and to select the
CT option.
And long press for confirmation
C.T. (Current Transformer)
C.T. Rate (Current Transformer)
To set the primary current ratio in the meter you must
program the divider into the meter. e.g. to set 200/5 amp
input “0040” (Divide the primary by 5) 5 amp being the
secondary of the c.t. See table below.
Options: 1~2000
Default CT rate 1. ( New Ratio Must Be Programmed Into
The Meter)
Long press to enter the CT Rate routine.
Press for 3s, the CT rate setting will flash.
Use and to choose CT rate with 1~2000.
And long press for confirmation
C.T.2 (Current Transformer)
Set C.T.2 secondary current input.
Options: 5A or 1A
Default CT2: 5A
Long press to enter the CT2 routine.
Press for 3s, the CT2 setting will flash.
Use and to choose CT2 with 5A or 1A.
And long press for confirmation

IMPORTANT NOTICE
The HT-1095 is a MID approved panel meter, once you have altered any of the
parameters e.g. Current transformer ratio or voltage ratio and you have come
out of the programming mode you cannot alter them again.
This rule does not apply to the Modbus settings.

Indication only
Electrician
The HT-1095 panel meter should only be installed by a fully qualified electrician who
has knowledge of electricity meters connected with current transformers.
It is the installer who is fully responsible for the safe installation of this meter. It must
be installed to meet the current electrical regulations concerning installation of panel
meters.
EMC Installation Requirements
Please see full installation brochure for details - visit autometers.co.uk
Wiring Information
Power Supply
The HT-1095 receives it power from any one of the voltage connections and Neutral.
Wiring
Electrical and communication connections are made directly to the back of the
meter.
The electrical connections of voltage, current and Pulse output are made directly to
the back of the meter. The RS 485 Modbus connections are at the top on the side of
the meter.
All terminals are green in colour and can be unplugged, The current terminals are
screwed in but can be unplugged if the screws are removed
Electrical Connections
2.5mm flexible stranded cable is recommended for all main electrical connections.
For the low voltage communication connections we recommend a twisted shielded
cable Belden 9841 2 wire or 9842 4 wire or equivalent.
Phasing and polarity of the AC current and voltage inputs and their relationship is
critical to the correct operation.
Dimensions
The meter is a 96 x 96 mm panel mounted meter with a depth of 70mm
The cut out hole for the panel meter is 92 x 92 mm.
