● Long battery charge life for a limited volume and weight.
● Possibility of quickly recharging your battery.
● Signicantly reduced memory effect: you can recharge your battery even if it is not fully discharged.
● Respect for the environment: no pollutant materials such as lead or cadmium, in compliance with the applicable
regulations.
After prolonged storage, the battery may be completely discharged. If so, it must be completely recharged. Your
instrument may not function during part of this recharging operation. Full recharging of a completely discharged battery
may take several hours.
NOTE: In this case, at least 5 charge/discharge cycles will be necessary for your battery to recover 95% of its capacity.
To make the best possible use of your battery and extend its effective service life:
● Only use the charger supplied with your instrument. Use of another charger may be dangerous.
● Only charge your instrument at temperatures between 0° and 40°C.
● Comply with the conditions of use dened in the operating manual.
● Comply with the storage conditions specied in the operating manual.
NiMH technology allows a limited number of charge/discharge cycles depending signicantly on:
● The conditions of use.
● The charging conditions.
Do not dispose of the battery pack with other solid waste. Used batteries must be entrusted to a qualied
recycling company or to a company specialized in processing hazardous materials.

of the same type and have the same ratio, the instrument simulates the third sensor by assuming the same characteristics
as for the two others. The third sensor will be shown in the list as either being simulated, or impossible to simulate.
The current probe choices that are available are:
MN93 clamp: 200AAC
MN193 clamp: 100 or 5AAC
SR193 clamp: 1000AAC
J93 clamp: 3500AAC/5000ADC
AmpFlex® A193: 100A/6500A/10,000AAC
MiniFlex® MA193: 100A/6500AC
MR193 clamp: 1000A/1200AAC/DC
SL261 clamp: 100A (sensitivity 10mV/AAC/DC)
SL261 clamp: 10A (sensitivity 100mV/AAC/DC)
Three phase adapter: 5AAC
If an MN193 clamp (5A range) or an adapter is used, the current ratio setting is proposed automatically. If an MN193
clamp (5A range), an Adapter, an AmpFlex®, a MiniFlex®, J93 or an SL261 clamp is used; adjustment of the ratio, range,
or sensitivity is proposed automatically.
Use the arrow buttons to dene the ratios between the primary current (1A to 60,000A) and the secondary current (1A,
2A or 5A), then conrm the selections with the button. Note that the primary current cannot be less than the secondary

The change from one of these representations to the other is automatic, as a function of the zoom level. If zoom in is high
enough, the representation is of the “waveform” type. The display depends on the type of display lter:
● 4V: displays the four voltages during the inrush current capture for set-ups with neutral (for a waveform type
display only).
● 3U: displays the three voltages during the inrush current capture for set-ups without neutral (for a waveform type
display only).
● 4A: displays the four currents during the inrush current capture (for a waveform type display only).
● L1, L2 or L3: display the voltage and current of phases 1, 2, and 3, respectively (only for set-ups with neutral and
for a waveform type display).
● N: displays the neutral current and neutral voltage during the inrush current capture (for a waveform type display
only).
● V1, V2, V3: displays the three voltages during the inrush current capture for set-ups with neutral (for an envelope
type display only).
● U1, U2, U3: displays the three voltages during the inrush current capture for set-ups without neutral (for an
envelope type display only).
● A1, A2, A3: displays the three currents during the inrush current capture (for an envelope type display only).
