Controls and Connectors
See Figure 1 for location of controls and connectors.
1. HOLD — Holds or "freezes" the measurement
display.
2. OFFSET -- Offsets the Measurement. This subtracts
the last two digits from subsequent measurements.
3. Vf1-01- (or VO-41- ) — Input for measuring volts,
ohms, diodes, and continuity. (The DMM157 also
measures capacitance.)
4. COM — Input for the common (ground reference)
connection.
5. mA — Input for measuring current up to 200 mA.
6. 10A — Input for measuring current above 200 mA.
7. Rotary Switch — Selects the multimeter function:
volts, ohms, diodes, continuity, or amperes. (The
DMM157 also measures capacitance.)
8. AC/DC, D/LPfl — Selects AC or DC voltage, AC or
DC current, high- or low-power ohms.
9. RANGE, RESET — Press this button to select one
measurement range. Hold it down for 2 seconds to
return to auto range. This control will also restore the
display after automatic power off.
10. Digital Display — This liquid crystal display (LCD)
has a maximum reading of 1999 (33. digit). The
display indicates auto range, auto polarity, decimal
point, overrange, AC (DC implied), 0/LPO,
measurement units, hold, and offset.
