IM 3201–E

 Measurement

· Do not apply a voltage or current over the allowable limits between the 

terminals.

· Do not apply a voltage to the measuring terminals when measuring DC 

currents (DC mA).

 Power source of measured objects

· A voltage may be applied to metals or wires that are connected to electrical 

equipments. Connect the measuring terminals after confirming that a voltage 

has not been applied, and the same applied to the grounding systems.

 Battery

· If the instrument is not used for a long period, store it with the battery removed. 

Otherwise, any leakage from the battery may damage the instrument.

 To avoid the risk of injury to personnel including electrical shock or damage to the 

instrument, carefully observe and follow the instructions listed below.

Notice Regarding This Instruction Manual
1. The contents of this instruction manual are subject to change without prior notice.

2. All rights are reserved by Yokogawa. No one is allowed to make copies of, reprint 

any part or all the contents of this instruction manual without permission from 

Yokogawa. 

3. If any questions arise or errors are found, or if any information is missing out from 

this manual, please inform us.

4. Yokogawa is by no means liable for any damage resulting from the misuse of this

CAUTION

CAUTION

· To avoid deterioration or damage to the circuit components, keep out of direct 

sunlight and do not use or store the instrument in locations subject to high 

temperature and high humidity including inside vehicles.

· Both sides of the front cover of the tester have been treated with antistatic coating. 

Use of a wet cloth for wiping the cover shall be avoided since it degrades the 

coating. Wipe softly with a dry sheet if the cover gets dirty. Use of volatile solutions 

such as thinner, benzine, or other chemicals shall also be avoided.

· The case and the tester cover are made of thermoplastic resin. Keep the 

instrument away from any high temperature heat source (e.g. a soldering iron).
