Ranger 7
Load Impedance:
Three settings by toggle switch.
X0.5 =700 ohms
X1 = 350 ohms (1standard load cell)
X4= 87.5 ohms (4 load cell platform)
Output Range:
0-3mV/V in .01mV/V steps (300 precision fixed steps)
Switchable Vernier:
Two Ranges
Range 1 is equal to the 0.5mV/V switch plus 0 -0.5mV/V.
Range 2 is equal to the 0.5mV/V switch plus the 0.1mV/V switch plus 0-0.1mV/V. Enabled by
pressing the switch.
Switchable Offset:
Off or switch setting ±25μV/V. Enabled by pressing the switch.
Accuracy:
±0.01% + 1μV of selected range
Zero Setting:
Position Zero returns the output to zero regardless of the switch settings. Offset setting remains
constant (if enabled).
Zero Offset:
±0.0005 mV/V

LED Annunciators:
EXC+ – normal Excitation Polarity.
EXC– – reverse Excitation Polarity. Both are on with AC Excitation.
OFFSET ON – the offset pot is enabled.
0.5mV/V – the variable pot is enabled with a range of 0 to 0.5mV/V plus the 0.5mV/V Rotary Switch
setting.
0.1mV/V – the variable pot is enabled with a range of 0 to 0.1mV/V plus the 0.5mV/V and 0.1mV/V
switch settings.
Binding Posts:
Type 2758 (by Low Thermal Electronics Inc.) precision gold plated low thermal EMF 5-way binding
posts for highest accuracy. Standard banana jacks at 0.75
” Pitch, or up to 14 AWG wire.
