Introduction
The HT-1095 is a multifunction energy
analyzer and is the latest in a new
generation of MID approved intelligent
panel meters used not only in the
electricity transmission and power
distribution system, but also in the
power consumption measurement and
analysis in high voltage intelligent power
grid.
The HT-1095 is capable of measuring
electricity in one phase two wire, three
phase three wire or three phase four
wire electrical systems.
The meter is a 96 x 96mm panel
mounted meter designed to be easy to
use and easy to read, the meter comes
with five control buttons for scrolling
and programming with a large back light
display for ease of reading. See picture
opposite.
The meter displays the following
information: Voltage, Frequency,
Current, Power active and reactive
energy, imported or exported, Power
factor, Max. Demand and Harmonics
distortion measurement on current and
voltage to the 63rd.
Energy is measured in terms of kWh,
kVArh. Maximum demand current can
be measured over preset periods of up
to 60minutes. In order to measure
energy the unit requires voltage and
current inputs.
The HT-1095 is a 1 amp or 5 amp current
operating measuring device and can
only work with current transformers.
Due to the design of the HT-1095 it is
fully programmable via the front keys to
enable a wide range of settings to match
any current transformer manufactured.
The Information Centre can be supplied
with a pulse Output or Autometers RS
485 Modbus protocol v.6.
Configuration is password protected.
This document provides operating,
maintenance and installation
instructions for the Autometers HT-1095.

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.

1.4 RS485 Serial-Modbus RTU
This unit uses a RS485 serial port with Modbus RTU protocol to provide a means of remote
monitoring and controlling. Please check section 5.2 for the details of setting.
1.5 Pulse output
Two pulse outputs indicate real-time energy measurement. Pulse output 1 is configurable, pulse
output 2 is fixed to active energy, 3200imp/kWh.

Long press , the CT2 setting will flash.
Use and to choose CT2 with 5A or 1A.
5.3.2 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 section 5.3.3 for the table.
Options: 1~2000
Default CT rate 1. ( New Ratio Must Be Programmed Into The Meter)
Long press to enter the CT Rate routine.

Example of how the display should look for a meter programmed to 200/5 amp.
See table for more settings.
5.4 P.T. (Voltage Supply)
The meter has been designed to work in 3 phase 4 wire or a 3 phase 3 wire
network and this requires a primary and secondary voltage ratio input.
The default is a 3 phase 4 wire configuration.
Long press to enter the PT2 routine.
For example:
A 3 phase 3 wire, 11000/110 Volt configuration:
Set the secondary (P.T.2) to 110 and the “RATE” (P.T.1 multiplier) to 100.
(110 X100 = 11,000)
5.4.1 P.T.2 (voltage supply)
Set secondary voltage input the meter
Range: 100V ~ 480V
Default: 230V ( L-N)
Long press for confirmation.
5.4.2 P.T.1 (Primary Voltage)
Set primary voltage input the meter
Range: 1V ~ 2000V
Default: 1
Then press to enter the PT1 routine.
Long press , the PT1 setting will flash.
Use or , to select PT1.
Long press for confirmation.
