1. Overview

The TD‑35 is a digital strain indicator that suits various strain gauge base

sensors, used for the indication of pressure, load or torque as well as the

load‑cell. This offers the display resolution of ±20000×10‑6 strain. In

addition to the display in strain unit, it is also capable of converting the value

into a real unit such as in Newton (N) using the preset sensor‑output‑value (mV/V)

for direct reading convenience. This operates with a built‑in battery (AAA type)

or external AC power supply (using an AC adaptor).

2. Features

1) Small and compact size.

2) All necessary functions for the static strain indicator are equipped and

ready to make a measurement simply by connecting the sensor.

3) Suited for almost all types of strain gauge base sensors such as load and

pressure.

3. Configuration

1) Pre‑amp 6) Bridge power supply

2) A/D converter 7) Operation controller

3) Display circuit 8) Internal battery

4) Ref. power circuit 9) AC adapter

6. Operation

6.1 Functions and controls in rear panel

① DC IN ‑ External Power Input Connector

The power input connector when AC power is used.

Use the supplied accessory AC adapter for the external power.

② POWER ‑ Power Switch

The power switch for the internal battery or the external power.

When the external power is connected, the internal battery is used and not

consumed.

③ LIGHT ‐ Back‑light Switch for LCD

The ON/OFF switch for the display back‑light. Note that twice as much power

is consumed when it is turned on in battery operation.

④ INDICATION ‐ Display Unit Switch

The switch to select whether the strain input is displayed in strain unit

(STRAIN) or the mV/V input is displayed in user defined unit (USER).

When STRAIN is selected, it displays in strain quantity (x10−６ strain),

and when USER is selected, it displays in user defined quantity.

⑤ ZERO ‐ Zero Cancel ON/OFF Switch

The ON/OFF switch of the zero cancel operation.

When it is ON, the zero cancellation is performed by pressing and holding ⑬

"SELECT" on the operation panel and press ⑨↓"ZERO‑RESET".

When it is OFF, the zero cancel operation is not performed and it displays

the strain quantity with reference to the TD‑35 internal zero in the selected

display mode set in ④. This can be used to check the initial balance value

of the strain gauge or strain gauge sensor.

⑥ INPUT ‐ Sensor Input Connector

The NDIS standard input connector for the strain gauge sensor. Applicable plug

model is PRC03‑12A10‑7M10.5 made by Tajimi‑Musen.

6.2 Operating Function and Controls

⑦ ↑ Key

Used to increase the setting value

⑧ → Key

Used to move the digit during setting value

⑨ ↓ Key (ZERO‑RESET)

Used to decrement the setting value or zero cancellation when used together

with ⑬ key.

⑩ ← Key

Used to move the digit while setting value

⑪ ENTER Key

Used to set the value in various settings

⑫ PEAK HOLD Key

Used to select the peak hold operation

It holds and displays the maximum value of the A/D sampling data. During

the peak hold operation, [P] is displayed in the LCD. When [P] is displayed,

press this key again and [P] disappears indicating that the peak hold mode

is canceled, the display mode returns to normal.
