WARNING

• Beforeconnectingthepowercord,ensurethatthesourcevoltagematchesthe

rated supply voltage of the MV and that it is within the maximum rated voltage

range of the provided power cord.

• ConfirmthatthepowerswitchisOFFbeforeconnectingthepowercord.

• Topreventelectricshockorfire,besuretousethepowercordsuppliedby

protective ground terminal.

• Donotuseanextensioncordwithoutprotectiveground.Otherwise,the

protection function will be compromised.

Use a power supply that meets the following conditions:

Item Condition

Rated supply voltage 100 to 240 VAC

Allowable power supply voltage range 90 to 132, 180 to 264 VAC

Rated power supply frequency 50/60Hz

Allowable power supply frequency range 50/60Hz±2%

Maximum power consumption 45 VA (100V) and 60 VA (240 V)

Note

Do not use a supply voltage in the range 132 to 180 VAC, as this may have adverse effects on

measurement accuracy.

Connection Procedure

 CheckthatthepowerswitchisOFF.

Connect the power cord plug to the power connector on the rear panel. (Use the

powercordthatcomeswiththepackage.)

 Checkthatthepoweroutletmeetstheconditionsgiveninthetableaboveandthat

the supply voltage is within the maximum rated voltage range of the power cord

thatcomeswiththepackage.Then,connecttheotherendofthepowercordto
