3.15 Zero-Adjust Function

Execute zero adjustment befor measuring to nullify any residual offset voltage from the instrument or measurement environment. Measurement accuracy specifications are applicable after zero adju stment.

Zero adjustment is a function which adjusts the zero point by deducting the

residual value obtained during 0Ω measurement. For this reason, zero adjustment must be performed when connection is made to 0Ω. However,

connecting a sample with no resistance is difficult and therefore is not practical. In this respect, when performing the actual zero adjustment, create a pseudo

connection to 0Ω and the adjust the zero point.

Wiring principle for Zero-Adjustment

The voltage between Sense(Red) and Sense(Black) becomes 0V according to the Ohm’s Law of E=I*R. In other words, if you set the voltage between

Sense(Red) and Sense(Black) to 0V, this gives you the same state of 0Ω

connection. Before executing zer o adjustment, connect the test leads ( probes) as follows:

1. Connect Sense (Red) to S ense (Black).

2. Connect Source (Red) to Source (Black).

3. Connect Snese(Bl ack) and Source(Black) .

Note

The detailed information for test leads probes, please refer to the test lines introduction.

Sine the amount of zero adjustment varies with the position and state of the

Function and Features

Copyr ight © Ite c h Electronics Co., Ltd. 31

measurement leads (probes) (i.e., their length, shape, position, etc.), the measurement leads must be positioned in the actual mea surement state befor e performing zero adjustment.

Wiring Method for Zero-Adjustment

3.17 ERR Output

The ERR output signal indicates the occurrence of measurement fault conditions (such as open test leads, or a bad conta ct).

There are two ERR output methods.  Synchronized with EOM Output (Sync)

Measurement faults detected while measuring (not while awaiting trigger or during delay or calculation intervals) , are indicated by ERR output synchro nous with EOM output(the end-of-measurement signal).

ERR output LOW (On): A measurement fault has prevented correct measurement.

ERR output HIGH (Off): Correct measurement obtained (OF or –OF: Out-of-range cases are included)

 Asynchron ous with EOM Output (ASync) Measurement faults (test lead connection conditions) are output in real time. The output is asynchronous wit h the TRIG
