T3DAQ1-16 User Manual

Input Terminal Protection Limitation

Protection limitation is defined for the input terminal.

1. Main Input (HI and LO) Terminals

HI and LO terminals are used for Voltage, Resistance, Capacitance, Continuity, Frequency,

Diode and Temperature measurement. Two protection limitations are defined:

•HI-LO protection limitation: 1000 VDC or 750 VAC. This is the maximum measurable

voltage. The limitation can be expressed as 1000 Vpk.

•LO ground protection limitation: LO terminal can “float” 500 Vpk relative to the ground

safely. The maximum protection limitation of HI terminal relative to the ground is 1000

Vpk. Therefore, the sum of the “float” voltage and the measured voltage can’t exceed

1000 Vpk.

2. Sampling (HISense and LOSense) Terminals

HISense and LOSense terminals are used for 4-wire Resistance measurement. Two protec-

tion limitations are defined:

•HISense-LOSense protection limitation: 2000 Vpk.

•LOSense-LOSense protection limitation: 2 Vpk.

3. Current Input (I) Terminal

The Iterminal is used for current measurement. The maximum current which can go through

the Iterminal is limited to 10 A by the fuse on the back panel.

NOTE: Voltage on the current input terminal corresponds to voltage on the LO terminal. To

keep good protection, only use a fuse of the specified type and value to replace this fuse

T3DAQ1-16 User Manual

IEC Measurement Category II Overvoltage Protection

To avoid the danger of electric shock, the Data Acquisition Unit provides overvoltage protection for

line-voltage mains connections that meet both of the following conditions:

1. The HI and LO input terminals are connected to the mains under Measurement Category II

conditions described in the warning below.

2. The maximum line voltage of the mains does not exceed: 600 VAC for the instrument.

WARNING:

IEC Measurement Category II includes electrical devices connected to mains at an outlet on a

branch circuit, such as most small appliances, test equipment, and other devices that plug into a

branch outlet or socket.

The DAQ is capable of making measurements with the HI and LO inputs connected to mains in

such devices (≤600 VAC) or to the branch outlet itself.

However, the HI and LO terminals of the DAQ can’t be connected to mains in permanently installed

electrical devices such as the main circuit-breaker panels, sub-panel disconnected boxes and per-

manently wired motors. Such devices and circuits are prone to exceed the protection limits of the

DAQ.

Limits for Measurements on Other Circuits Not Directly Connected to Mains

Max. rated input voltage: 1000Vrms

Transient overvoltage: 4000Vpk

WARNING:

Voltages above 600 VAC can only be measured in circuits that are isolated from mains. However,

there may be transient over voltage in circuits that are isolated from mains. The DAQ is able to

withstand occasional transient overvoltage up to 4000 Vpk. Please don’t use this instrument to

measure circuits where transient overvoltage may exceed this level.
